...123#124# Events are read from the socket's event pipe only on the thread that125# the 0mq context is associated with, which is the native thread the126# greenthreads are running on, and the only operations that cause the127# events to be read and processed are send(), recv() and128# getsockopt(zmq.EVENTS). This means that after doing any of these129# three operations, the ability of the socket to send or receive a130# message without blocking may have changed, but after the events are131# read the FD is no longer readable so the hub may not signal our132# listener.133#134# If we understand that after calling send() a message might be ready135# to be received and that after calling recv() a message might be able136# to be sent, what should we do next? There are two approaches:137#138# 1. Always wake the other thread if there is one waiting. This139# wakeup may be spurious because the socket might not actually be140# ready for a send() or recv(). However, if a thread is in a141# tight-loop successfully calling send() or recv() then the wakeups142# are naturally batched and there's very little cost added to each143# send/recv call.144#145# or146#147# 2. Call getsockopt(zmq.EVENTS) and explicitly check if the other148# thread should be woken up. This avoids spurious wake-ups but may149# add overhead because getsockopt will cause all events to be150# processed, whereas send and recv throttle processing151# events. Admittedly, all of the events will need to be processed152# eventually, but it is likely faster to batch the processing.153#154# Which approach is better?
