userspace memory

[Schmidt András]

Hi!

My question is that how much memory can an OpenMoko userspace 
application use?

Certainly I see on wiki that the device has 128M of RAM. The question is 
how much is consumed by the operating system when it is used "normally" 
(eg when talking or writing SMS) and how much remains for a user program 
to use?

I am developing a map viewer application that loads the tiles (from 
flash or internet) of maps when they are accessed. These tiles are then 
disposed but some could also be cached (for the chance that the user 
scrolls to the same area again). I am trying to find out what cache size 
I could use.
