I didn't try the code yet, but:

If the child fails on the `execlp', you should use `_exit' instead of 
`exit'.

It looks like the message will be written twice if `waitpid' fails.

Also, it's possibly better to pass the string to xmessage via a pipe 
instead of the command-line, although since you're not using `system' 
anymore, it's not as important.
