Strange - if I have no personale customizations left, what could be
the difference that makes the bug reproducable on my system and
irreproducable on yours?  Should I mail the complete output of
`cygcheck -c' on my machine, the list of XP patches installed or
something similar?

Anyway, your patch for the crash of mutt when being suspended fixes
the zsh problem, too - it's gone after upgrading to snapshot 20040221!

I was just guessing for the usual suspects - if it's not the cygwin DLL,
a memory management bug in zsh triggered by the latest changes in the
Cygwin environment seemed like a plausible candidate to me.

As the crashes are fixed by snapshot 20040221, should I investigate
further (in case another bug is lurking behind the scenes), or can
we consider this file closed?
