  Log Message:
  -----------
  tm: check branches that should be cancelled under lock

This fix avoids race condition between a CANCEL message and replies that
are coming in the same time.

Thanks go to Tommy Brecher for reprting this and offering extensive logs
to debug the issue in ticket #1759.
Credits for the fix are shared with Bogdan Iancu for the brainstoring.
