Please note that while ksh supports co-processes it doesn't use (to my
knowledge) the keyword 'coproc'. - Kornshells co-processes are invoked
by appending the '|&' token to a command and reads and writes are done
with 'read -p' and 'print -p', respectively.

Seems to be pretty much the same thing, but with a slightly different
notation (|& vs. "coproc").  I think the original bash designers wanted to
be at least sort of "csh compatible", so they took |& from csh to mean
"merge stdout and stderr", so had to come up with something else for
coprocs.

Anyway, all I know about ksh is basically what I've read from various bash
sources.
