I do understand your hesitation on this.

However, fork will never work for dynamic loads -- the loading app will 
get very confused at this, and I suspect the same for exec and popen as 
well, so the problem is moot for dynamic loads.

My proposal still stands since it won't modify the behavior of cygwin
linked apps in any way, only change it for dynamic loads.

Mumit
