[Evolution] Question about evolution task "alerts"

[Sean O'Neill <sean seanoneill info>]

I'm running on Suse 9.0 Pro with Evolution 1.4.5.  Currently just using 
Evolution for Calendar and Tasks.  I've noticed at times there are the 
following tasks in my ps listing even when I don't have evolution running:

soneill linux:/var/mail> ps -ef|grep evolution
soneill   2730  2622  0 Mar25 ?        00:00:03 
/opt/gnome/libexec/evolution/1.4/evolution-alarm-notify 
--sm-config-prefix /evolution-alarm-notify-5cXpTP/ --sm-client-id 
117f000002000107962174300000027010009 --screen 0

Are processes like these related to evolution trying to throw up a popup 
window saying a task is about to start/end or whatever ?

If they are, I've never seen any sort of window popup from Evolution.

Any thoughts appreciated.
