The test_sendfile_fallback_close_peer_in_the_middle_of_receiving test in test.test_asyncio.test_sendfile.SelectEventLoopTests fails with error “OSError: [Errno 41] Protocol wrong type for socket” intermittently on macOS. I have seen this error multiple times across Python 3.8-3.11rc1 CI...

ENH: use non-trivial bounds to solve for kappa of vonmises MLE.

6

#### Reference issue This is a follow-up commit for gh-18190. #### What does this implement/fix? The MLE of the vonmises distribution solves $r_0(\kappa):=I_1(\kappa)/I_0(\kappa)=r$ for $\kappa$ given $0 < r <...
