I recently discovered that emacs has a bunch of zombie subprocesses.
A bit of experimenting reveals that if I run

(call-process "/bin/sleep" nil 0 nil "5")

then this returns immediately, as expected, but after 5 seconds, the
subprocess becomes a zombie and never goes away.

Is this the intended behaviour, or a bug? Should I file a bug report?

It's a bug.  Please file a bug report.  Sigh, and I just put a change
into emacs-24 that may trigger the same bug.  I'll try to look into
it later today, but I don't have easy access to OS X so this may
well require some help.

I can reproduce this on Cygwin (on the emacs-24 branch with your latest change), so it's not just an OS X issue.
