[PATCH 5/6] perf session: Move the global threads list to perf_session

From: Arnaldo Carvalho de Melo
Date: Sun Dec 13 2009 - 16:51:43 EST

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

So that we can process two perf.data files.

We still need to add a O_MMAP mode for perf_session so that we can do
all the mmap stuff in it.
