[Buildbot-devel] buildbot from git hangs during setup until slave connects?

Murphy has truly blessed me with his presence today.

On an Ubuntu 10.04 host, running VMWare player 5.0.0, and inside that
Ubuntu 12.04, and installed on that buildbot from git (fresh from git
this morning), my buildbot master gets part of the way through
startup, then hangs on adding the first scheduler (a force scheduler, hmm!)
before it starts up the web status listener.

Two things will unstick it:
1) if a slave connects (or if I telnet to the slave port)
2) if I strace the process (with strace -p)

W, I say, TF?

I don't recall this happening before.

The master I'm running is at
