Removing one more memory leak found with valgrind.
If you are spending time one memory consumption by perf-top one thing to
look at is handling of terminated threads. Currently, terminated threads
are stuck onto the dead_threads list and only cleaned up when perf
terminates (perf_session__delete_dead_threads).
Since the thread entries can still be referenced in hists perhaps a
refcnt is needed that indicates when the threads can be deleted. From
there regular calls to perf_session__delete_dead_threads can be made. I
needed to add a regular call to that function in my perf daemon to keep
memory usage stable - but then I don't have lingering references.
A lot of work yes but will be needed if there is to be an official
libperf.so that apps can leverage.
