Andrew, should I re-send this patch? It was acked by Daniel and Dave doesn't object.
Dave, I'll appreciate it if you ack it explicitly.

It is hardly possible to enumerate all problems with block_all_signals() and unblock_all_signals(). Just for example,
block_all_signals(SIGSTOP/etc) simply can't help if the caller is multithreaded. Another thread can dequeue the signal and force the group stop.
Even is the caller is single-threaded, it will "stop" anyway. It will not sleep, but it will spin in kernel space until SIGCONT or SIGKILL.
And a lot more. In short, this interface doesn't work at all, at least the last 10+ years.

Probably best to go via Andrew alright.
Dave.
