Log message:
	integrate sigaltstack technique from:
	see http://www.engelschall.com/pw/usenix/2000/pmt-html/
	so now AMD64_DARWIN user threads work (Juno starts up)
	AMD64_DARWIN 10.5 doesn't support get/set/make/swapcontext
	getcontext returns -1 and errno=ENOTSUP
	(does it work on 10.4 or 10.6?)
	will enable for OpenBSD after testing
	integrated right into the Modula-3 layer instead
	of implementing get/set/make/swapcontext
	(some unneeded generalization remains, will cleanup)
