[Buildbot-devel] Builders that use latent slaves start in a state "building"

[Pierre Tardy]

It is a complication on how the latent build slave was patched in. There is
no state recorded that the build request is claimed but waiting for a
latent slave. Build is not yet created at that time. Creating one is a
possibility. In case of latent slave start failure we ll have to mark it
RETRY.

You may want to file a bug and if you are brave enough start working on it!
The brd is a complex subsystem but very interesting to work on. You ll have
to work on nine though add this is too intrusive feature for eight.
