# Example where a pool of http servers share a single listening socket
|
|
#
|
|
# On Windows this module depends on the ability to pickle a socket
|
|
# object so that the worker processes can inherit a copy of the server
|
|
# object. (We import `multiprocessing.reduction` to enable this pickling.)
|
|
#
|
|
# Not sure if we should synchronize access to `socket.accept()` method by
|
|
# using a process-shared lock -- does not seem to be necessary.
