Odd stack frame (race) condition on py 3.10

[goodboy]

I can hit this traceback on py3.10 on the latest release:

 File ".../tractor/310/lib/python3.10/site-packages/pdb.py", line 1227, in xpm
      post_mortem(info[2], Pdb)
    File "...tractor/310/lib/python3.10/site-packages/pdb.py", line 1175, in post_mortem
      p.interaction(None, t)
    File "...tractor/310/lib/python3.10/site-packages/pdb.py", line 216, in interaction
      ret = self.setup(frame, traceback)
    File "...tractor/310/lib/python3.10/site-packages/pdb.py", line 259, in setup
      ret = super(Pdb, self).setup(frame, tb)
    File "/usr/lib/python3.10/pdb.py", line 217, in setup
      self.curframe = self.stack[self.curindex][0]
    IndexError: list index out of range

However it seems to be resolved in b757794 (I haven't bisected any further back yet) so running off master seems to resolve it.

Just wondering if this was fixed intentionally and when we can expect a release to cover it 🏄🏼

Linking goodboy/tractor#165 as source discovery.

Related to #482?

Yeah maybe it was just the one major version?
I'm not sure.

For now this is being worked around by taking master commits but sure would be nice to get a release 😉
