3be31f5dcb Include <unistd.h> and <sys/resource.h>. 
(KB): New macro.
(big): Lower the size to 64*MB.  Should be enough for another year... ;-)
(gettime): Fix typo and lower the assumed cache-line size from 64
	to 8 bytes just to be safe across platforms.
(measure_init): Lower N from 1000 to 100.
	(cursor): Add some padding between each unw_cursor_t to avoid
		benefitting from cache-line sharing.
	(uc): Likewise.
	Warm up the TLB before measuring the cold-cache cases.
(main): Unlimit the max. stack-size just in case.
	Write to "big" to ensure it's backed by real memory
	(not just by the zero page).

	registers, since those are outside of the rotating partition.
