Bug with parameter module

[Peter Stephenson <pws@xxxxxxxxxxxxxxxxxxxxxxxx>]

Somebody must know more about why this should be happening.

zsh -c 'zmodload -i parameter; fn() { exit 1; }; fn'

The shell hangs.  It seems that executing fn uses some wrapper associated
with the parameter module which then won't unload.  There should be some
mode to force unloading on exit (this is the real problem worked around in
the case of zle by Clint's patch in 8862, I would think).
