Dave Sparks 23c21baf27 Hold a lock while we access the preview heap. ... copyFrameAndPostCopiedFrame was not holding a lock while it accessed the preview heap. If the client process is torn down while the heap is accessed, the memcpy could access memory that was deallocated. This patch creates a local sp reference to the preview heap while holding the lock, then releases the lock. This should prevent the heap from being pulled out from underneath us.		2009-11-06 11:47:13 -08:00
