I don't know if it's related, but SimpleXMLRPCServer in Python 2.7 uses
fcntl(self.fileno(), fcntl.F_SETFD, flags):
class SimpleXMLRPCServer(SocketServer.TCPServer,
SimpleXMLRPCDispatcher):
...
def __init__(self, ...):
...
# [Bug #1222790] If possible, set close-on-exec flag; if a
# method spawns a subprocess, the subprocess shouldn't have
# the listening socket open.
if fcntl is not None and hasattr(fcntl, 'FD_CLOEXEC'):
flags = fcntl.fcntl(self.fileno(), fcntl.F_GETFD)
flags |= fcntl.FD_CLOEXEC
fcntl.fcntl(self.fileno(), fcntl.F_SETFD, flags)
=> see also issue #1222790.
