Cygwin Filesystem Performance degradation 1.7.5 vs 1.7.7, and methods for improving performance

[Derry Shribman]

Hi,

The xstat() is useless for the target of improving performance: it will takes 
YEARS after Linux kernel will implement it until typical unix applications will 
use it all around their code - just like other 'relativly new' kernel APIs like 
epoll() took years until unix applications started adopting them.

Do we want Cygwin to be slow for another 10 years?!

The env variable is a practical immediate way to improve performance with very 
little effort.
