The Scavenger currently requires taking the lock for OLD->NEW processing
and can also take another lock for sweeping a different page.

Since order of pages during scavenge and sweep is unstable this may
result in lock order inversion reports on TSAN when long-running
programms are only executed on a single thread.

The report is a false positve, hence flag it as suppression until we
redesign this particular piece.
