The ​implementation for ConditionVariable::Add calls another function that locks a static mutex, and I've no idea how that could be uninitialized or the like. So I'm not sure what's going on here.

The implementation I linked above is the one for the kernelland_emu (whoops.) The real one had what looked like a disturbing amount of spinlock contention. Following hrev53336, that should be fixed (though there was a bug in it that I fixed in hrev53337.) So if you can test after that hrev, it will be very interesting to see if this is improved at all.

Can you please retest this on a recent nightly?
