Reece Wilson 433898709e [*] Check for null handle under LSHandle bc win32 apis are inconsistent as shit
[*] _beginthreadex returns null, nonex returns -1, and it doesnt fucking work with affinity but seems to work with name updates. i dont care to fix this yet. fuck microsoft.
[*] NT: preempt process watch thread of leaders instead of syncing to the process under a watch guard on free (evil, we should use a builtin nt threadpool. also cant be arsed to resolve)
