Whether 1.7 is faster or slower depends on what you're doing and on what
OS you're running.  For instance, scanning local directories is about
60% faster in 1.7 while starting lots of processes is about 10% slower
on Vista but about 5% faster on XP, according to my testing.  Further
optimization will be a task for post-1.7.1, while for 1.7.1 itself we're
looking primarily for functionality.

Having said that, if you find source code in Cygwin which could be
improved, feel free to point it out.
