This is a problem with Emacs closing the compilation buffer and killing
all sub-processes after the compilation process finished (It is done
by `call-process' [C function] so it is not easily solved). Just add
"sleep 3" at the end of your script and you'll see all your sub
processes output.

A real workaround is to run the subprocess with `nohup' and directing
its output to a file (You won't be able to see it in Emacs buffer 
because Emacs closes the pipes after the process terminate).

Ehud.
