We were talking about mobile devices ...

These days every business billing and accounting suite I know of --
and we _make_ a bookkeeping suite, which we need to interface
with many other things ....

runs in its own VM and doesn't share with anybody.

multiplayer games tend to run in their own VM as well, and too many
users using the game can and does degrade performance.  But I don't
think that having too many users flush their stream objects is a
significant part of this problem, compared to the problems of
getting your bits out of your graphics card, for instance.
