On non-Windows platforms, the default was to use multiple receive threads, which in turn implied the use of blocking read operations. On termination, those blocking calls were interrupted by sending a packet to itself, but that only works if the firewall allows it. If the firewall drops these packet, the process hangs. Various people have run into this problem, changing to using a single thread always solves the problem. So, changing the default until a better solution for interrupting these calls is implemented is probably for the best. Signed-off-by: Erik Boasson <eb@ilities.com>
