Actor pool "join" returns too early

[jeberger]

If one of the actions already running tries to send a new action to the pool after the main thread has called join, then the new actions may not get called.

import actors

var
  a: TActorPool[int, void]
createActorPool(a)

proc task (i: int) {.thread.} =
  echo i
  if i != 0: a.spawn (i-1, task)

a.spawn (10, task)
a.join()

This code should print all numbers between 0 and 10 in no particular order, instead it only prints "10".

Reopened because tests indicate it still works not reliable.

Closing for now, tests appear to fail because of output capturing issues.
