He wasn't proposing how ZMQ_AFFINITY works. Any change would be to accommodate the arbitrary-length bitmask used for assigning I/O threads to CPUs. There are already machines available that have *more than* 64 CPUs or cores, so the uint64 used by ZMQ_AFFINITY could only address up to 64 I/O threads. I can't imagine a case right now where it would be necessary to do so, but then again 640k of RAM is enough for everybody, right? :)
