When multi-thread is enabled, the machine->threads_lock is contented
as all worker threads try to grab the writer lock using the
machine__findnew_thread(). Usually, the thread they're looking for is
in the tree so they only need the reader lock though.
Thus try machine__find_thread() first, and
When multi-thread is enabled, the machine->threads_lock is contented
as all worker threads try to grab the writer lock using the
machine__findnew_thread(). Usually, the thread they're looking for is
in the tree so they only need the reader lock though.
Thus try machine__find_thread() first, and
