When a process is ptraced, it will often be set to TASK_STOPPED by the
kernel. However, any process in the same session can start the ptraced
process by sending a SIGCONT signal. Is this intended behaviour? IMO,
it seems like we loose some control over the ptraced process by
allowing this.
The reason I bring this up is because I want to use ptrace to set
capabilities on a process to avoid races. This requires that the
ptracing process actually has control over the ptraced process.
