I presume that the child process which ran the script ends quickly. Considering
the comments below, the quick finish seems to be a consequence of what the
script argument is (and possibly because that app. is a terminal).
Try as I might though, I cannot get it to work for

Such a script works AFAIK (I minimally tested with opera and a html file), but
in this case the child-process running the script persists until the
argument(s)/application ends - which defeats your purpose.

No.
On my (very limited) understanding, zombies can be created when child processes
are not properly cleaned up. Hence the warning dialog.
BUT I have once seen an invalid warning about a process that was actually
finished, I'm trying to find how that happened.
