[users at bb.net] Scripting a pausing of all build slaves/workers

[Pierre Tardy]

Ah, so what you really need is cleanshutdown of master

buildbot stop -c

this will make sure the master does not accept any more build, and stop
when all builds are finished.
or you can send a SIGUSR1 (which is equivalent)
