On my part. Here's a way we can dodge the whole neonate, infant
mortality nonsense.
Instead of marking everything dead at the beginning of a DOD run,
which'll get us the most aggressive cleanup, we mark things dead at
the *end* of the run. Then we also allocate all our headers marked as
live on allocation, and make sure there's some minimum number of free
headers after the end of a DOD run to make sure we don't collect too
soon.
This'll mean we don't have a neonate problem, though we trade that
off with having all headers live through at least one DOD sweep. We
can, if we want, have a separate DOD routine that does the mark as
dead first (and last) that the explicit DOD trigger op can use so we
don't have to worry about things living longer than they should.
We could call them conservative_DOD and aggressive_DOD or something
along those lines, if we wanted.
