You haven't gone nearly far enough in that direction. The proposed
output still relies on the assumption that the session will always
get as many workers as it asks for, which it will not. For previous
bitter experience in this department, see for instance commits 4ea03f3f4
and 13e8b2ee8.
TBH I am not sure that the proposed regression tests for this change
can be committed at all. Which is a bit of a problem perhaps, but
then again we don't have terribly good coverage for the existing code
either, for the same reason.
