If he insists on using the IDLE feature, the client will be waiting
for unsolicited I/O, like a server, so he may need wait_for_objects()
in order to respond to application message events as well.
With SSL, I suppose one would have to be careful to check for pending
data in the SSL buffer before calling wait_for_objects.
