    perf tools: Reference count struct thread · f3b623b8

    We need to do that to stop accumulating entries in the dead_threads
    linked list, i.e. we were keeping references to threads in struct hists
    that continue to exist even after a thread exited and was removed from
    the machine threads rbtree.
    
    We still keep the dead_threads list, but just for debugging, allowing us
    to iterate at any given point over the threads that still are referenced
    by things like struct hist_entry.
