Thanks @edmorley!

Race conditions were just in tests, not library code. Changes were [here](https://github.com/nteract/zmq-prebuilt/commit/45538aea828c02c9376df97a3d694f381ce08a55).

Yeah, probably. I was thinking I'd like to avoid having to write and install an extension here (so that doesn't need to be duplicated across repos) before doing that, but...

This sounds like a bug that should be reported to libzmq, since it's not related to pyzmq. I guess ipc messages can drop when sockets close, apparently ignoring LINGER. You...

Confirmed this is still an issue on openbsd 7.4 with libzmq-4.3.5. I'm building with cmake. autotools builds seem to work. compilation command that fails in cmake: ``` /usr/bin/c++ -DZMQ_CUSTOM_PLATFORM_HPP -D_OPENBSD_SOURCE...

#4659 avoids the error in default configuration when building with cmake by fixing the headers required to look for kqueue. This error can be reproduced with autotools, built with `--with-poller=poll`

I think this is a bug in libzmq, unless I'm mistaken. When you bind to a random port, it's really doing: ```python s.bind('tcp://127.0.0.1:*') url = s.last_endpoint # tcp://127.0.0.1:12345 ``` and...

It seems a bit silly that only pure Python packages can be green, when most of the value of wheels is in compiled binaries that can't ever have universal wheels....

> Just curious - why never? Linux has sensible package managers, and it has generally been the opinion of core Python folks that binary distributions on Linux should be done...

@jasongrout's remembering our conversations at least as well as I do, but I still agree. The main reason we don't shutdown kernels on close in nbclassic is that notebook close...
