As you see XP and Win7 now a really faster.
Win7 3x speed - wow.

I will test ist.
I've already recognize one positive side effect:
The CTRL-C Handler works now even faster.
With unpatched cygwin1.dll there was a realy long delay, after pressing CTRL-C.
Can you agree this too?
I'm very interested if this patch will be released or not.
I'm interested in the opionion opinion of C. Vinschen and C Faylor.
