Hi Darin,

to add to our little Mozilla chat here, and to what Rob and Ben said:

If you have several builders, i.e., build processes, those can share a
slave. By default, those will run in parallel.
If you want multiple builds of one builder on a slave, that's not
possible. There is one build per builder per slave at a time. You can
run multiple buildbot slave processes on one machine, though.
If you want only one build to run on a particular slave at a time,
independent of the builder, then you either have to use slave locks
like Ben said, or wait for the .6 release. Buildbot trunk has an
optional parameter for BuildSlaves, max_builds, which limits the
number of concurrent builds of any kind per slave, on a slave basis.
http://buildbot.net/trac/browser/buildbot/scripts/sample.cfg#L17 is a
good link to the sample.cfg right now.
