If it's just a matter of starting vlc and trying to kill it for you,
then there's something more to track down since this doesn't happen for
me (Fedora 9).

There must be more to it than simply zsh not waiting for children:  that
has no effect on whether vlc is executing code.  The propagation of the
signal to the programme seems to me a likely suspect.  Of course these
could be related to the same fundamental problem.  vlc does appear to do
some fairly odd things with signals which may be interacting in
unexpected ways with the shell.

It would be useful to know whether the vlc job is listed in the shell's
job table at this point, and to see what else is there.  The array
jobtab contains the jobs, which contain linked lists of process
structures.  One of the jobs (it should be the one indexed
by curjob) should include the vlc process.  The previous bug
happened because some other job (marked as defunct) had
a process with the same number.
