64 is the limit for the total number of objects (listening ports, connections to a port, client connections, your console, the waker, serial ports, whatever) that WFMO may wait upon at once. Put another way, MAXIMUM_WAIT_OBJECTS=64: http://msdn.microsoft.com/en-us/library/ms687025(v=vs.85).aspx _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
