In this case watching the build wouldn't have helped, since the
buildbots stayed green (I had misinterpreted Dean's original message,
the tone of which he has since apologized for).

However, to answer the general question, you should not completely
trust the try server.  If the try server breaks, it's a very good
indication that an actual commit would break, but the reverse is not
true.  If the try server succeeds, it doesn't mean that a commit will
succeed, since the try server runs fewer tests (and there may be
commits to the tree in between doing a try and doing a commit).  So
even if the try succeeds, it's still important to watch the buildbots
to make sure the actual commit also succeeds.  That wasn't the problem
in this instance (you wouldn't have seen this failure), but I wanted
to make sure people don't rely too much on the try server.  It's a
good "preflight check", but it won't catch everything.
