Before you're running `compinit', the function-based completion system
is *NOT* online yet. Zsh will fall back to the older compctl system.

When you say "no reaction" do you mean that zsh eats up all CPU or does
it actually hang without and CPU utilisation at all?

If NFS is in play it could also be bad performance with certain options.
Does the shell hang or does completion just take a very very long time?
As in "minutes"?

Sounds weird. Can't identify a reason off hand.

There is nothing in there, that would cause that I think. The other
files (zshenv, zprofile, zlogin - global and user-only) are empty, I
presume?

My *guess* is that something triggers user-name lookups which may take a
very long time with a lot of users in networked environments. But like I
said, it's a guess for now...

Sorry for taking so long. I'm pretty swamped with other work right now.
I hope the other guys from the maintenance team will chime in. ;-)
