Timeout of threads of callbacks cause errors

[sotte]

The error callback when joining a channel that one has no access to, i.e., :error is returned by phoenix, throws an error:

channel = socket.channel("project:no_access")
channel.join()\
    .receive("error", lambda _: sys.exit())

This is the error:

Exception in thread Thread-3:
Traceback (most recent call last):
  File "/usr/lib/python3.4/threading.py", line 920, in _bootstrap_inner
    self.run()
  File "/usr/lib/python3.4/threading.py", line 1184, in run
    self.finished.wait(self.interval)
  File "/usr/lib/python3.4/threading.py", line 553, in wait
    signaled = self._cond.wait(timeout)
  File "/usr/lib/python3.4/threading.py", line 293, in wait
    if timeout > 0:
TypeError: unorderable types: function() > int()

Whereas joining a channel successfully works:

channel.join()\
    .receive("ok", lambda: print("Successfully joined"))

I haven't had time to debug it. I'll just write it down and add more information later.
