I have an issue when running "openssl speed" on either a 64 bit Windows 7 PC
(Intel Core i7 870 2.93GHz) or a 64 bit Windows 2008 R2 Std Server (Xeon
X5450 3GHz) under Cygwin. "openssl speed" runs fine on all the other *Nix's
I manage.

It hangs either after the first line or maybe the next 6 or 7 lines, it's
variable. I tried doing a time on the command and it didn't complete after
over an hour where I had to Control-C to stop the execution.

Surprisingly, when I perform a strace on the executable, it executes
successfully and the results from "openssl speed" look to be more than twice
as fast.
