Try the double-fork trick, that works in most of those situations. By  
double fork I mean the forked child process exists immediately after  
forking another process which does the actual work. This dis- 
associates the prent from the 'grandchild'. You may also have to  
close the open file descriptors (STDIN, STDOUT, STDERR) in the child.
