Like MadeInGermany, I'm not a MAC user either so I'm now going to talk generic Unix/Linux only. You will need a MAC expert to guide you if you want to use anything I'm going to say now.
Many Unix/Linux OS's implement an often undocumented command called clri which will destroy an inode (by writing zeros to it). A nuclear option. A quick search on Google tells me that MacOS implements this command too. I also see that it implements fsck_hfs.
Therefore my final nuclear option on an OS I'm expert on would be:
1. Ensure that you have just completed a backup of the filesystem (and perhaps preferably the whole system) and know how to restore if it goes wrong. Keep users off afterwards.
2. ls -li has given you the inode number of zombie so run clri to nuke it. BE CAREFUL to specify the correct filesystem on the command line if you have more than one filesystem otherwise you could zap the wrong inode. I cannot give you the MacOS syntax. Try man clri to see if it's offically documented.
3. Once the inode is nuked go into single user mode and run fsck_hfs. The allocated blocks for zombie should show as "missing blocks" and the utility should ask your okay to fix the superblock.
Now I repeat, this is a generic suggestion and you should await input from a MacOS expert on here as to whether they think this method is a goer. I take no responsibility whatsoever but it is how I would fix such a problem on some Unix/Linux filesystems.
This will be my last post to this thread because I'm out of my comfort zone.

talk(1) General Commands Manual talk(1)
NAME
talk - talk to another user
SYNOPSIS
talk_party [ttyname]
DESCRIPTION
The utility is a two-way, screen-oriented communication program.
The command argument talk_party can take one the following forms:
user
where user is a login name and host is a host name.
The optional command argument, ttyname, can be used to specify the terminal to be used when contacting a user who is logged in more than
once. In absence of this argument, will try to contact the user on the user's most recently used terminal.
When first invoked, sends the following message to the party it tries to connect to (callee):
...
At this point, the recipient of the message can reply by typing:
Once communication is established, the two parties can type simultaneously, with their output displayed in separate regions of the screen.
Characters are processed as follows:
o Typing characters from LC_CTYPE classifications print or space will cause those characters to be sent to the recipient's terminal.
o Typing <control>-L will cause the sender's screen to be refreshed.
o Typing the erase, kill or kill word character will delete the last character, line or word on the sender's terminal, with the action
propagated to the recipient's terminal.
o Typing the interrupt character will terminate the local talk utility. Once the talk session has been terminated on one side, the other
side of the talk session will be notified that the session has been terminated and will be able to do nothing except exit.
o Other non-printable characters typed on the sender's terminal are converted to printable characters before they are sent to the recipi-
ent's terminal.
Permission to be a recipient of a message can be denied or granted by using the utility. However, a user may need other privileges to be
able to access other users' terminals. The utility will fail when the user lacks the appropriate privileges.
