Like, and am proud of you guys (sniff), but don't want to ell gee tee em until
we can see the additional capacity of trybots go live.

capacity live, lgtm but need rubberstamp

Oh, this is a bigger increase than I expected.  By changing PRESUBMIT.py you're
also increasing the number of CLs we process by +65%.  you're still OK to land
but be ready to make revert if bots get overwhelmed

[Isaac (away), 2012-07-19 14:39:44]

nevermind, ignore the thing about +65%.  

PRESUBMIT.py only affects git try, was thinking the change was affecting
gatekeeper.  lgtm
