First of all, thanks so much for this AWESOME project! I'm trying to use it as a means of running through the various performance gates, so I can hopefully recommend other core developers do the same.
I'm going to assume this is something weird in my installation since I didn't see this reported anywhere else. However!
I'm trying to follow along with http://www.youtube.com/watch?v=Xjgwhn_SnZc and download the devel module from Drush. When I do it sits there and hangs for several minutes, then says file devel-1.7.2.tar.gz is corrupt. (md5 checksum mismatch)
This same thing happens for any other files I attempt to download that way, e.g. cck. However, all is well from my host machine.
