Q: IconServicesAgent RAM usage

(Note: I am aware that there is an existing thread about IconServicesAgent, but in that thread much of the discussion revolves around troubleshooting high CPU usage, whereas I am not having any issue with CPU usage.)

Basically, my system is running fine, but I would like to find a way to reduce the RAM usage of IconServicesAgent. I have been running Mavericks for several months, and still IconServicesAgent consumes over 300 MB of RAM pretty much all the time, even without any apps running and without any startup items. So, I have two questions: 1) Is it normal for IconServicesAgent to always use so much RAM? and 2) If it is normal, is there any way I can tweak my system to reduce IconServicesAgent's RAM footprint?

Below I include my EtreCheck report:
