Description

The heap grower thread just knocked out one of my cores. Unfortunately, I was still too sleepy to get a stack crawl; I hope this happens again.

More info, I get this one when it happens - it seems it's currently always reproducible when the app I'm currently working on crashes:

KERN: thread 1147 tried to acquire kernel semaphore 0.

From then on, the heap grower is always trying to acquire semaphore 0 which obviously fails every time. Maybe that semaphore is deleted from userland somehow, I'll have a look.

Indeed, the semaphore got deleted. Fixed in hrev29621.
