Howdy, Araneida uses a worker thread pool to generate its HTTP responses when running in threaded mode. In order to replenish the pool, it needs to determine whether a thread is "alive" in some metaphorical sense or is "finished". I know Dan has expressed reservation over some kind of general process state function, but I believe that alive versus finished is appropriate to all known threading systems, and furthermore necessary to be able to do serious work with thread pools. To that end I would propose that a predicate thread-finished-p should be added, which returns true when a thread is no longer eligible for execution, either by normal or abnormal termination.
