/* We're only wrapping vfork() as a poor man's pthread_atfork(). That would
* require dedicated linkage against libpthread. So here we force the locks
* to a consistent state before forking.
*
* We also implement vfork() as fork() because sandbox does not meet vfork()
* requirements bet ween vfork()/exec("some-static-bianary") because we launch
* ptrace in the middle.
