In an attempt to mitigate this problem, since pre-commit testing is a (the?) major bottleneck that we have at sprints, I will be bringing a nice fast machine with virtual machines for at least one flavor of each of our major supported platforms (OS X, Linux, Windows, FreeBSD).  I still need to install some dependencies, but hopefully I can do some whole-suite pre-commit verification for other reviewers who are there.

Hopefully the keyboard won't get too hot for me to type on :-).

For the next sprint, our BuildBot maintainer has assured me that he'll be moving the build master infrastructure to a faster machine before then, so that hopefully it will cope better with the increased load of a sprint.
