For the users out there, Safari is a bitch on memory if you close it with any tabs open. MobileSafari keeps running in the background and the memory it eats up is huge. Documented this here http://www.trending.us/2009/01/10/quick-tip-to-save-a-lot-of...

None of this would be needed if Apple did the right thing and added a garbage collector.

In the mean time, thanks for the links.

I'd love to read some commentary by someone who's really intimately familiar with the iPhone and its internal workings about the rationale for not having a garbage collector. I've seen Apple refer to performance, but.. how big an effect is it, really? If anyone here wants to have a shot at explaining it, go ahead! :)

Well, its only got 128MB ram and flash storage...so there is no virtual memory I suspect. I'm sure the OS takes a big chunk of memory, with the possibility of background tasks eating up more. With a garbage collected system, I'm sure you'd routinely see performance hits when the garbage collector runs as it frantically tries to free storage with low and fragmented memory conditions. Not to mention the extra battery drain to constantly scan the freeable pointers. This is an embedded device with big limitations...you need to be more mindful of resources.
