Wow, thanks.  Where is cygwin faster?  Is this a recent change is the
snapshot faster than 1.1.7?  Or is 1.1.7 faster than 1.1.4?  I did
add some code to read to bypass signal interruption if there were
no signal handlers present which should have some speed improvements
but that was added in 1.1.6.

I also just implemented SA_RESTART but I don't that would have an effect
on anything since it requires a reconfiguration and recompilation.

DJ also did some performance analysis and targetted some areas that
needed tweaking.  This should have shown up in 1.1.6.  I was never
certain that there was a clear improvement, though, or I would have
announced this as a 1.1.6 change.
