thread:destroy-thread thread[Function]

Destroy thread by sending it an interrupt which throws to the end of the thread giving it a chance to unwind gracefully.

Warning: The thread is not guaranteed to exit cleanly. For restrictions, see thread:thread-interrupt. When necessary, it is recommended that threads poll for exit events, such as an exit flag, and arrange to exit gracefully themselves.
