That's the plan. This bug takes me quite some time to analyse, so I
don't promise any quick success here. If anybody (Jim?) can comment on
my findings to prevent me running in the wrong direction that would be
very helpful.
Next step for me will be to verify the assertion that when calling
settid() it must be passed a strictly larger tid than the one before.
There is no test currently assuring this or the opposite. Once I find
out, I'll update the tests.
