Log message:
	implementation of direct thread suspend/resume for interix
	been sitting on it and almost deleted it
	
	direct suspend/resume can be achieve by writing certain control
	codes to the correct files in /procfs
	
	the context of a suspended thread can be gotten by reading a file
	
	However I'd like to at least avoid opening the files repeatedly.
	
	Here we open them in thread create.
	
	I don't remember why Interix can't use the portable code.
	It doesn't have SA_SIGINFO but that doesn't prove it.
	It is empirically showable that the context is on the stack.
	So maybe we just have a single parameter signal handler and a null context?
