[issue31169] convert_to_error assertion failure in multiprocessing/managers.py

Well, it looks like I was incorrect in where the AssertionError is coming from - the attached patches, while an improvement IMO on the current code, did not result in a change in behavior. Unfortunately, the combination of bare asserts (with no messages) with remote raising of errors makes it rather hard to debug - I will see if pdb will do it, but given that it's involving a subprocess I will be very impressed if it does. (Coverage.py frequently misses lines that are only executed in subprocesses, for instance.)
