I dont think so its rom dependent..
Every rom has this
However ... wid gb stock rom mediaserver used to run only for few seconds that to wid percentage (that was quite good n useful)
Bt then since ics... it has been pathetic...just do some modification in gallery and bang the phone starts heating up due to mediaserver running in background... also accompanied by battery drain.. :/
