[zeromq-dev] ZMQ_HWM handling: impossible to disable queuing

[Alexey Ermakov]

Hi,

Current semantics of ZMQ_HWM (0 = no limit) mean that it's impossible
to disable message queueing, which could be very useful in some
applications. It would be great if default value of ZMQ_HWM has been
changed to UINT64_MAX and ZMQ_HWM of 0 disabled queuing at all. Is
there any downside to it that I don't see (other than API semantics
change)?
