[issue27664] Allow specifying prefix for thread name in concurrent.futures.ThreadPoolExecutor

[Gregory P. Smith]

Gregory P. Smith added the comment:

A workaround for this on 3.5 and older versions is probably to do:

initialization:

num_q = queue.Queue()
map(num_q.put, range(max_workers))

Then schedule max_workers identical tasks:

def task():
  threading.current_thread().name = '%s_%d' % (your_prefix, num_q.get())
  num_q.task_done()
  num_q.join()  # block so that this thread cannot take a new thread naming task until all other tasks are complete.  guaranteeing we are executed once per max_workers threads.
