Bananymous adb14ba373 Kernel: Userspace signal handlers are now called one at a time 
I added a syscall for telling the kernel when signal execution has
finished. We should send a random hash or id to the signal trampoline
that we would include in the syscall, so validity of signal exit can
be confirmed.
