Three things the review turned up, no behaviour change:
Hold recomputed address.ToUInt128() three times where the original hoisted
it to a local. Restored.
Drain cleared _warnedFull on every iteration; it now clears once, after,
and only when something was actually retired. The store was inside the loop
whose cost this whole design exists to keep small.
Grow doubled without a ceiling, so a 324,449 cap reserved 524,288 ring slots
-- 4.8 MB that can never be used. Push only runs below the cap, so the ring
never needs more than maxEntries; growth is capped there. Progress is still
guaranteed: Grow is only reached when capacity == _ringCount, which is at
most maxEntries - 1 at that point, so the capped size is always larger.
Adds a test for that last one, since a cap that is not a power of two is
where a wrapped write would run off the end, and notes the new default in
the configuration table.
