I see how communicate() is convenient. I would argue that there are helper
libraries out there which allow you to make Lua builtin popen a lot  
more useful.

I used my own library lua-t which sports an event loop but I'm sure there is
other stuff out there which provides similar functionality.  Note, this is a
very quick'n dirty example without any error checking ...


local   Loop = require('t.Loop')

l = Loop(4)
h = io.popen( 'sleep 3 && date' )
l:addHandle( h, 'read', function( handle )
	print( handle:read( '*all' ) )
	handle:close( )
	l:stop()
end, h )
l:run( )
