Peter Bourgon	b585a362ac	Naïve process walker for Darwin ... This fixes the regression where process names weren't appearing for Darwin probes. Makes testing easier. Also, changes the process walker to operate on value types. There's no performance advantage to using reference types for something of this size, and there appeared to be a data race in the Darwin port that caused nodes to gain and lose process names over time. Also, restructures how to enable docker scraping. Default false when run manually, and enabled via --probe.docker true in the scope script.	2015-07-16 12:33:59 +02:00
