We hit a similar problem with sourceforge's 5-hour anoncvs update latency. My
advice would be to modify the Scheduler you're using to insert some delay
between the time the changes come in and the time the build is started. (the
tree-stable-timer is closely related, and can probably be used to accomplish
this, but the precise answer is to have a second timer that gets triggered
when the tree-stable-timer expires, which just puts off the submitBuildSet by
whatever the mirror's latency is).

Actually, given that sf.net does their anoncvs mirror push off a cronjob, we
could just write a Scheduler that knows the schedule of those jobs, and
arranges for a build to be started a few minutes after the mirror pulse.
Cheesy, but it would provide for an absolute minimum latency build...

Oops.. I'll take a look at this one later tonight.
