Once again, I must plug the "ex" API at
http://lua-users.org/wiki/ExtensionProposal .

Please have a look at the popen2() example on that page.  It's
implemented with io.pipe() and os.spawn(), both of which are provided
by Lua installations which provide the "ex" API.

The source code to the reference implementation is available on the
wiki, but an updated version will be available at
http://luaforget.net/projects/lua-ex as soon as the friendly luaforge
admins respond to my repository upload request ... ;)
