Doesn't work with the very old csh on Solaris. Tcsh supports it, as do
bash, zsh, and ksh (88 & 93). No idea when it was introduced in each,
though if ksh88 has it, I suspect all the bourne shell derivatives do,
except maybe the original bourne shell itself.
I'm guessing that pretty much everyone using an operating system that has
pkill available will be using a shell with $!, except maybe some csh users.
Csh users can be really, really stubborn. :)
But that's just a guess.
