I’m currently testing a version which has deltask delete the task’s deps
flag, and iterates over __BBTASKS to delete the task from other task’s deps
flags. My up front parse times aren’t changing, so it doesn’t seem to have
a great deal of impact on performance, which was my only concern with that.
The alternative, if the performance is an issue, would likely be to start
maintaining revdep information.
