I don't think any more the slow process creation (fork) I'm seeing is a
Cygwin problem. A Makefile for ActiveState Perl also takes an eternity
to run. The delay appears to be caused by time-consuming process
creation.

These Windows utilities also take time to launch. All processes, once
running, do *not* appear slow; they just take time to get started.

What can I do at the Windows or Cygwin level to find the cause of this
slowdown?
