The really big move to 1.7 is done.  In the next time the changes will
be more iterative again, if that's what you're asking.

other than that, we made no performance tests.  Some changes were meant
to make Cygwin perform better, some other to make Cygwin behave more
correct.  Sometimes these development goals collide.
