The sysmon thread is not related to asynchronous preemption. The sysmon thread does a few different things. One of the things it does is notice threads that have been stuck in a system call for a while, and detach them from their P, and start running a new thread associated with that P. This is scheduler activity, and it permits additional parallelism in the program, but it's not preemption.
