Right, here's whats happening:
SYSTEM doesn't belong to any network groups - it's local only, but
Cygwin is trying to find out it's network data - such as the home
domain.

Cygwin spawned/forked/execed process's can inherit that data in the
cygwin heap IIRC. Which is why no delay is seen - it's been optimised
away. But there would be a 30 second delay firing up bash.

As for why the 30 second delay in the first place, what's your system
config:
Are you a member of a win2k AD or an NT4 domain?
Are you running NBT?
Are you running NTLM?
Are you running the Server process?
Are you running the workstation process?

Cheers,
Rob
