I guess I don't really get the "in-process" part of this -- isn't
it necessary anyway to use a separate process in the general case?

E.g. to ensure _every_ resource currently held by the application
being debugged is dropped and obtained again from scratch (many of
those resources could be external-to-Python entities which -- it
seems to me, but I guess I may be missing something -- only an OS
level end-process-and-restart could ensure are dropped/re-obtained,
no?).  Maybe there could be some support for checkpointing a Python
based process and "restart-from-checkpoint" to ease this (now THAT
would be a dream, getting that "for free" from the infrastructure
rather than having to code it for each application that's meant to
run for a long time and must survive power loss/restart etc... not
just for debugging... but I find it somewhat hard to envision a
sufficiently-general mechanism, at least offhand).
