RE: Slow compdump on Vista - no .zcompdump created

It's usable although noticeably sluggish (and I have a 2.8GHz dual-core
machine with 4Gb memory!).
I've just posted to the cygwin mailing list about "ls" being much slower
on Vista compared to XP:

I did encounter the fork problem but ran "rebaseall" to fix things up.
Perhaps this rebasing has somehow contributed to the slowdown?

Does your question imply that zsh with cygwin is more or less functional
vista?  My experience with it, confirmed by many postings around the
is that the cygwin fork functionality is completely broken on vista and
makes zsh essentially unusable on vista.  Has there been a fix for this
problem, or has the situation changed for some other reason?

Thanks in advance,

Subject: Slow compdump on Vista - no .zcompdump created

Each time I start cygwin zsh (4.3.2 or 4.3.4) on Vista, compinit takes
around 12 seconds and no .zcompdump file is created:

C:\>zsh -f
$P$Gautoload -U compinit
$P$Gdate; compinit; date
Wed Oct 24 13:56:08 GMTDT 2007
Wed Oct 24 13:56:20 GMTDT 2007
$P$Gls .zcompdump
ls: .zcompdump: No such file or directory

"compinit -u" and "compinit -C" take about the same time.

With zsh 4.2.6 on WinXP, when I run "compinit" I get prompted:
  Ignore insecure directories and continue [ny]?

(this prompt isn't shown with zsh 4.3.{2,4} on Vista.)

If I type "y" or run "compinit -C" it runs much faster in zsh 4.2.6 on
WinXP (although a .zcompdump file is still not created):

$P$Gdate; compinit -C; date
Wed Oct 24 14:08:16 GMTDT 2007
Wed Oct 24 14:08:17 GMTDT 2007

Any ideas on how to speed it up on zsh 4.3.4 on Vista, and why the
.zcompdump file is not being created (`man zshall' states it should be
created by default)?
