Well, I was going to suggest loading the OSProcess stuff I posted a while
back, but it seems to have disappeared from the swiki again. I can
repost if there is interest.

OSProcess supports reading and writing stdin/stdout/stderr, and can
fork a headless Squeak to run your program. For example, you could run
your program by doing "UnixProcess forkHeadlessSqueakAndDo: aBlock"
where your program would be aBlock. The ReadStream on stdin is
"OSProcess forThisOSProcess stdIn" and the WriteStream on stdout is
"OSProcess forThisOSProcess stdOut", both of which are accessible
from the headless Squeak.
