run-tests: attempt to fix iolock handling

Ideally, when using -j and -i together, when a prompt comes up, we'd
like all other output to wait (but testing to continue!). This gets
other output to wait by adding back a bunch of the locking that
formerly existed. We switch to a recursive lock to deal with the
restructuring due to unittest compatibility.

Running tests continue to run, but now the scheduler doesn't schedule
any new tasks while waiting at a prompt because no task slots become
available due to result output happening in the thread and
blocking on the iolock.
