-1, a bug.\n\nSo I investigated this and noticed that when we introduced support for\nrecording a process and its threads using --pid some bugs were introduced and\nthat the way to fix it was to instead of passing the target_tid to the event\nsynthesizing routines we should better pass the thread_map that has the list of\nthreads for a --pid or just the single thread for a --tid.\n\nChecked
