The real problem appear to be that, nowhere in the Linux system reside information about the files than the vsftpd daemon is working with ...
Re paragraph 1: I find it very hard to believe that lsof can't do this. Your lsof could be broken, more more likely you are doing something wrong. Since you haven't mentioned stuff like precisely what command you used or precisely what result you got there's no way to tell. Could you take a bug report like: "'lsof' doesn't show the file" and do anything with it?

Re paragraph 2: "exclusive locks" are the only kind that exist. If you want a mandatory lock, read mandatory.txt. But this won't help much. If you do it correctly, you will succeed, and vxftpd will experience failed writes. It will probably detect this and inform the ftp client of the error.

Re paragraph 3: I wonder how the data gets to the file?

I looked at the source code for vsftpd. I see it has a logging option. Turn that on and parse the log to see if the file is finished.
