Subject: BG processes killed by start-process

Start-process seems to kill off child processes of which have been put  
into the background.

Create a small shell script "bgtest":

#!/bin/sh
sleep 121 &
exit 0

and now

(start-process "BGTEST" nil "bgtest")

Notice that the sleep process has been killed, rather than waited on.

Is this the intended behavior?  Any thoughts for preventing it (other  
than modifying the script, which I don't control)?

Thanks.
