o Major bugfixes (conflux):
- Fix a relay-side assert crash caused by attempts to use a conflux
circuit between circuit close and free, such that no legs were on
the conflux set. Fixed by nulling out the stream's circuit
back-pointer when the last leg is removed. Additional checks and
log messages have been added to detect other cases. Fixes bug 40827;
bugfix on 0.4.8.1-alpha.
