- Regarding adding a break in addDeadWatcher.We basically do not interrupt
the caller thread of addWatcher during the shutdown. So the caller thread will
not be interrupted during the shutdown.
-The caller thread of addWatcher can be interrupted out side of the
shutdown. Do you recommend break and adding watcher even it reaches max pending
watchers or return without adding watcher?---
