Finally this makes a cancelled root actor nursery not clobber child tasks which request and lock the root's tty for the debugger repl. Using an edge triggered event which is set after all fifo-lock-queued tasks are complete, we can be sure that no lingering child tasks are going to get interrupted during pdb use and tty lock acquisition. Further, even if new tasks do queue up to get the lock, the root will incrementally send cancel msgs to each sub-actor only once the tty is not locked by a (set of) child request task(s). Add shielding around all the critical sections where the child attempts to allocate the lock from the root such that it won't be disrupted from cancel messages from the root after the acquire lock transaction has started. |
