This should have been check_process="${procname} /bin/sh".

This is incorrect.  The sguil-server port creates, and the 
sguil-sensor port creates

However, I'm still having the problem of the second process's startup 
failing because it thinks the pid already exists.  (Doesn't matter which 
process you start first.)  Any hints would be appreciated.
