The recent problem was to do with what happens if the child is reaped 
elsewhere, and so using fclose() instead of pclose().  (My, that was a bugger 
of a bug to track!)  What's wrong with just having another flag in the 
userdata to say it's a popen, rather than guessing when you call close(), I 
don't know.
