Revert^4 "Add spin loop to mutex, overhaul monitor"
This reverts commit ead89ef62768faa06fedd279b86bccbed1464673.
PS1 is identical to Revert^2.
This fixes a shutdown issue caused by prematurely hanging when we
block while trying to acquire system mutexes during shutdown.
Only refuse to wake up after shutdown is well under way.
