We talked about this possibility during this summer's GSoC project to
design a new master/slave protocol.  In Buildbot as it stands, the
complicating factor is the protocol, which includes the notion of a
builder (and corresponding slavebuilder) and assumes only one build
runs on a builder at any one time.  This is also why the slave
pre-creates the directory for each builder on startup. IMHO that
doesn't make a lot of sense - it's not hard to create a directory when
it's needed!

I don't think that's the answer you wanted, but if you do have the
resources to work on the new protocol, it would benefit not only your
case but lots of others, too.
