[Buildbot-devel] Waiting for two builders to finish before triggering a third

[Philippe McLean]

(a suggestion)

introduce a new builder A that is scheduled by commits.
A has steps:

1. trigger [X, Y], wait for finish
2. trigger T, wait for finish
3. report

The waterfall display will look a bit more confusing but A would be your
'master build'.
