71 container is busy before checking whether capacity allows for
72 a further insertion. Insertion in a busy container that is full

4597 time from Vulnerable_Complete_Master "for convenience" (i.e. to
4598 kill off tasks waiting at terminate alternatives), aborting
4599 indirect dependents is wrong, because it causes some unrelated
4600 tasks to get aborted.
