While generally true, this isn't the case. The heart beat thread is
run by appkit.

Subject: NSProgressIndicator thread safe?
Hi everyone,
one of my user has its MBP crashing on me, I just can't figure what
the problem is, here's the crashed thread:
Thread 5 Crashed:

Is it because NSProgressIndicator isn't thread safe?
