Signal numbers are typically represented as ints.  Is there anything in
the kernel that prevents me from, say, calling kill(2) with a second
argument of, say, 0xdeadbeef, in other words any old random int value
that I might care to use?

If not, then there are effectively 4 billion+ different signal numbers
that could be used by a programmer.  Such usage might not be fully
standard-conformant, but it might work OK, nontheless.  (In fact, one
might even be able to use _most_ typical pointer values as if they
were signal numbers, simply by casting them to ints before use.)
