Thanks for the interesting suggestion, Benoît.  I actually tried this, and the
push to Mercurial reported that Buildbot was notified:

  [default] $ hg push
  pushing to https://...
  searching for changes
  remote: adding changesets
  remote: adding manifests
  remote: adding file changes
  remote: added 1 changesets with 1 changes to 1 files
  remote: Notifying buildbot...

Unfortunately, the notification never actually showed up in Buildbot (and,
thus, no build was triggered).

But thanks for replying.  :)
