It's strange it would use 8833 twice, but I guess system startup is
deterministic.  I looked around a bit, but Bonobo is complex, and I
ran out of time trying to figure out whether oasd's port is hard

If IDLE's port was registered in /etc/services, might that
prevent oasd from grabbing it?  Or is services just advisory?

In any case, IDLE is indeed hard coded to 8833.  That's in
PyShell.py:ModifiedInterpreter(), around line 322.  There should be no
problem changing it to, say, 8843 if that solves the problem.  Just
run IDLE as root with the -n switch, load the PyShell module, change that
line, and try again.

In the future, IDLE will find another port if one is in use.  That
will pave the way for running multiple IDLEs, and also fix this
