28 ptrace commands from the tracer is called ptrace-stop. Ptrace-stops can
29 be further subdivided into signal-delivery-stop, group-stop,

35 When a (possibly multi-threaded) process receives a killing signal (a
36 signal set to SIG_DFL and whose default action is to kill the process),
37 all threads exit. Tracees report their death to the tracer(s). This is
