| - | Suspends (or freezes) a running thread. Returns success and an error message on failure. A "suspended" thread never autonomously wakes up and dies as soon as its parent process (if attached) closes. A suspended thread ignores events. That means any event listeners or timers created inside the thread will not respond to event notifications. Note that threads do not buffer event signals and a suspended thread may miss event signals it was waiting for. For example, if a thread was last waiting on `event.pull("modem_message")` and is "suspended" and a "modem_message" is received by the computer then the thread will miss the event and never know it happened. | + | Suspends (or freezes) a running thread.
