Right now, the weather panel applet does not call "exit" on the 
weatherservice.  This is probably because you could run the reportviewer 
or the weather bar in konq and both would require starting the service 
again.

I'm surprised that exiting the weatherservice makes that  much of a RAM 
difference.  Here are the numbers from my machine from top. 
21557 kde-deve   9   0  4968 3372 2392 S  0.0  1.3   0:11.18 kweatherservice
virtual: 4968
res: 3372
shared: 2392

I'm no memory expert, but isn't the amount of unique RAM for this 
process the res number minus the shared number?  If so, It's about a meg.

It would be nice if those numbers were lower.  I only have 256 mb 
myself, and I was thinking about taking a look and optimizing the RAM 
usage of kweatherservice, but I haven't had a chance yet.

In any event,  are you proposing that each service have a watchdog type 
timer that would time out and exit the service?  Or would the dcop 
system handle the timeout knowing that no services have been requested?  
What would the timeout be?  Half an hour?
