Log message:
	allow building cygwin and openbsd/x86 user thread variants
	even if they don't work yet -- provide stubs for the old
	implementation strategy, to ease providing a new strategy;
	ultimately the two will probably both coexist in the source
	with a constant as to which to use, at least temporarily
	as platforms are migrated
	(note that cygwin doesn't provide setitimer so won't work with
	current plan)
	
	some rename/restructure of C code for terseness, not
	done previously because I didn't think it'd work, and it
	still doesn't seem to work consistently
