If you can't back up your conclusions with actual code why should we
assume that you are infallible?  No one is that trustworthy.

There has been very little actual data provided here beyond the "It must
be bad because Microsoft doesn't turn it on by default" argument.  Since
Cygwin uses all sorts of things that Microsoft doesn't turn on by default,
I assume that, by extension, most of cygwin is really bad.

Thank you.

Lets use the popular reasoning here.  If there was no potential gain
then Microsoft would not have provided the option, would they?  Since
they did there has to be *some* potential gain.

Thanks for not mentioning that you think a CYGWIN environment variable
option is the way to go for this.  I guess we're making minor progress
