FWIW this is now done in bitbake master. The IPC between the workers and
the server is implemented and working well too which avoids a whole raft
of problems.

I think I'm going to switch Poky to bitbake master soon and drop 1.8
there - we're getting much closer to the 1.10 release, just need to look
at those parsing changes and fix a BBCLASSEXTEND issue.
