I ran into this too, after I bumped my zshrc to the newest grml zshrc
on Debian Stable with NFS home and about 5000 users in NIS. So I'm not
sure if it has the same reason, but it definitely has the same
symptoms.

I'd say 5 to 10 minutes or so. Ctrl-C doesn't help. Just waiting. The
zsh process is in the "uninterruptable sleep" state (aka "D" aka "disk
waiting").

It doesn't seem to happen with all kinds of completion but at least
with scp completion.

I think the direction is the right one...
