On a freshly installed and configured Windows XP machine with a fresh
install of a recent Cygwin, we noticed that every non-builtin command
took about a second to start.

The PATH started with /usr/bin:/bin as the first dirs, and then also
included much later a symlink to a samba shared script area
(/usr/local/script --> //samba/script).

On this particular machine, just having /usr/local/script in the PATH
slowed down *every* command.  Even commands like "ls", much earlier 
in the path suffered the problem.

Any idea why?  I ran an strace on rxvt (which is how I diagnosed the
problem - saw what it was doing the output streaming past stopped).

Any idea why this machine (same network, same domain) has this problem,
and others don't?

Here's a dramatically trimmed down bit of the strace output:
