	* heuristic to go farther during stack traces.
	* significantly improved Linux thread handing.

acid:
	* update to new libmach interface.

prof:
	* use new libmach interface.
	* multiple thread support (derived from Rob's copy).
	* first steps toward pprof-like graphs:
	  keep counters indexed by pc,callerpc pairs.

trying to find all the places where
spans might be recorded.
