Not a problem, but thread HashMasher-3 could not immediately reserve a core, it may experience decayed performance.
Not a problem, but thread HashMasher-4 could not immediately reserve a core, as there are no more cores to assign to. If performance is degraded, attempt with fewer hashers.

This is probably fatal, so exiting now.
