I rewrote the function responsible for the slow startup, the one
fetching all the group information for the groups in your user token.

As I just wrote in my mail to Dennis Hagarty, the performance improvement
should be noticable, even with /etc/nsswitch.conf only using the "db"
setting for groups.  The group info for a user token with 150 groups was
fetched in ~50 ms rather than the ~300ms of the former code.

Can you test this again with the Cygwin DLL from the latest developer
snaphshot at https://cygwin.com/snapshots/ please?


Thanks,
Corinna
