Actually I tried that in the past and it has drawbacks that made me give 
up on it. First you may allocate a lot of memory. Assume 50 processes 
each with 5Mb. That makes 250Mb wasted as only 1 process really needs 
more memory, that is the main process which loads the dialogs at startup 
(or the location entries). All the other workers do not need that extra 
memory so it's just wasted. Then later you find out that 5Mb is not 
enough because you have too many dialogs so when you hit a new limit you 
have to increase it again and recompile. It's simply not working.
