Re: Cygwin: environ problem

I'll reply to both cygwin-related messages in one go:

Without some major rewriting, we may have to: the export-related machinery
assumes it has direct control of the (new) environment's memory.  This is
certainly a contender for the problems people have been seeing.  Strange it
usually works, though.

Is there any chance this could be network-related?  My desktop PC has lots
of Samba-mounted drives in various paths, and completion is an absolute
pig, at least until things are cached.  I installed cygwin and zsh onto
someone's notebook this week, with no network dependencies, obviously, and
it's as fast as `normal', whatever normal means for a UNIX porting layer on
top of NT.  There are no serious network problems here which could cause
the difference if everything's running properly.
