Andreas Kling 2a65f0ee4f strace: Allow "strace command" to trace a process from start to finish. ...

Tracing a specific pid is now done via "strace -p PID".
To ensure we don't miss any syscalls, we fork and have the child immediately
SIGSTOP itself. Then when the parent has set up the systrace() fd, we send
SIGCONT to the child which then execs the command. :^)
