[Buildbot-devel] Can't get a slave to pick up more than one request at time

[Jim Rowan]

That’s what we do as well.   It seems like a hack, but it’s effective, at least.    In doing so, you may want to pay some attention to ensuring that the build factory being run doesn’t actually *do* a lot of work itself — because it doesn’t own the machine in the same way that a “normal” one would.

The fact that builddir has by default the builder name in it kinda makes sense. If a slave allowed multiple builds from the builder they would end up clashing.
