FIXME below. If we are above DISPATCH_LEVEL we queue a DPC Else, we just delete it immediately. Until I can figure out what overwrites the processor DpcData, we immediately free GDB Freezes immediately when I put a watchpoint on any address, I fucking hate and i cannot stress how much I hate GDB debugging with QEMU since its so buggy, i wish i had windbg..
