Subject: [PATCH 0/4] perf: Fix leaked events when sigtrap = 1

While looking at task_work users I just noticed that perf doesn't flush
its own upon event exiting. This looks especially problematic with child
events. Please have a thourough look at the last patch, I may easily
have missed something within the maze.
