so we only context switch when a packet is available, then we acquire the semaphore to do the actual work. Ideally the entire system would be async IO but this is a good compromise. > I don't know what priority it runs as, but could you figure it out by > attaching a debugger and setting a breakpoint and then examining the thread > in the Watch/Expressions windows?
