FYI, you can look in /var/log/setup.log -- it keeps track of every setup
invocation and is appended.  For the details of the last upgrade, see
/var/log/setup.log.full

You could use the "strace" utility to see where the delays are...  Also,
see if you have network paths in your PATH, as mentioned in
<http://cygwin.com/faq/faq.html#SEC33>.
