I'm not sure how to try out a test release without risking destabilizing my system, but I re-cloned and rebuilt the master branch and installed just the cygwin1.dll and all looks good to me so far.   No issues with any of my script pipes or fifos and I am getting full gigabit speeds with rsync.  

I too have been following all the pipe rework on Cygwin-developers and want to express my appreciation for Takashi, Ken and Corinna for tackling this.    You folks have made Cygwin so much more usable for a lot of applications!
