I don't really think it does.
I remember when I first got my phone it was FW 1.1.1 and it seemed to get hot when I was doing lots of things... bouncing around between text, email, youtube, safari. It seemed like it would get overloaded, and in those times, closing programs with the 6-second-home-button thing worked to alleviate the problem.
I have to say I haven't experienced anything like that from 1.1.2 on, I believe. I think Apple did something to more efficiently allocate resources dynamically. I think now, apps in the background are relatively dormant to the point where, for all intents and purposes, they are closed.
I have no actual evidence to this fact, other than I know Apple is being strict about SDK apps not being allowed to run in the background. Who knows.
