I wasn't aware that any systems provided such an interface. Thanks.
Looks like AIX supports it as well.
nohup Command
Hopefully the OP consulted his man pages soon after posting.

If the script was started with bash or ksh93 (perhaps other shells as well), the
disown built-in can be used. This ensures that the interactive shell won't send SIGHUP to that job's process group if its controlling terminal is closed (which is usually the source of a SIGHUP). Note that this does not modify any process' signal mask, so if a SIGHUP arrives from somewhere, the process will be terminated.

NOHUP(1) BSD General Commands Manual NOHUP(1)
NAME
nohup -- invoke a utility immune to hangups
SYNOPSIS
nohup [--] utility [arguments]
DESCRIPTION
The nohup utility invokes utility with its arguments and at this time sets the signal SIGHUP to be ignored. If the standard output is a ter-
minal, the standard output is appended to the file nohup.out in the current directory. If standard error is a terminal, it is directed to
the same place as the standard output.
Some shells may provide a builtin nohup command which is similar or identical to this utility. Consult the builtin(1) manual page.
ENVIRONMENT
The following variables are utilized by nohup:
HOME If the output file nohup.out cannot be created in the current directory, the nohup utility uses the directory named by HOME to create
the file.
PATH Used to locate the requested utility if the name contains no '/' characters.
EXIT STATUS
The nohup utility exits with one of the following values:
126 The utility was found, but could not be invoked.
127 The utility could not be found or an error occurred in nohup.
Otherwise, the exit status of nohup will be that of utility.
SEE ALSO
builtin(1), csh(1), signal(3)
STANDARDS
The nohup utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
BUGS
Two or more instances of nohup can append to the same file, which makes for a confusing output.
