From 35feee19f9fda7447f51073b5be3f6d082b508f5 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Sat, 28 Sep 2013 13:12:58 -0600 Subject: perf machine: Add method to loop over threads and invoke handler Loop over all threads within a machine - including threads moved to the dead threads list -- and invoked a function. This allows commands to run some specific function on each thread (eg., dump statistics) yet hides how the threads are maintained within the machine.
