Bananymous 925df39107 Kernel: Userspace sets the foreground process and Shell handles ^C 2023-07-28 18:10:36 +03:00
Bananymous 2dce0a0415 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.
