I've semi-convinced myself that pthread_[gs]etspecific do not need signal
protection so I've released a snapshot which turns it off:
http://cygwin.com/snapshots/
This version is about 2.7 times faster than cygwin 1.5.17 but it is still
not as fast as mingw. I don't think we're going to hit mingw performance
since there are still cygwin overhead issues involved.
AFAIK, this is only going to provide a speedup for this specific case.
I don't think a general cygwin user is going to notice any improvement.
