Hi,

I do not agree to this changes. For a non system thread, we use a kernel
mode apc first, which uses a second user mode apc. This overhead isn't
necessary. For system threads it isn't possible to use a kernel mode apc
which calls PspExitThread. A system thread must terminate it self. It is
only possible to help by marking a flag, setting an event or unwait the
thread.
