SIGQUIT(3) handler calls lock already held.

Looks like too much is being done during a signal handler. I was lead to send this signal(over SSH) by likely deadlock on this mutex.
This lockup(Oxygen Not Included/native) is highly reproducible and results in the game being unplayable after reaching a certain point, number of buildings perhaps.
