My speeds are even slower than those posted:

I am running cygwin 1.5.25, Windows 2008 x64 on a Intel Core 2 @ 2.13ghz.
One CPU is maxed to 100% when forking. This speed explained why opening bash
took as long as 10 seconds, and I wanted to find out why it was so slow.
Is it possible to profile the implementation easily?
