I regularly use the testing framework to run code I am working on and use
pdb/ipdb to halt the execution and do some "manual" testing.
In parallel testing mode I was not able to do that, as the pdb.set_trace()
statement exits automatically. I guess that this is could be expected and
maybe desired behaviour, but if not it would be nice to be able to ipdb
into tests run in parallel as well.
It took me a while to find the reason for the automatic exits, so if its
not possible to pdb into parlallel tests, maybe adding a line or two in
the documentation about this could be helpful for others.

There is no way this can work. We should document this as a known
limitation.
