In todays world, SMP is becoming more and more common (still waiting to
get that DualCore cell phone). So that means that writing to a variable
is going to carry more weight than it use to, and gcc needs to take note
of this. So, to avoid a short condition jump by adding a write to
memory, is not going to save anying.
In general shared variables are going to be pretty rare, and its
reasonable for gcc to assume they aren't. But it would be nice to have
a good way to solve cases like this (though it seems like (condition) &&
__warn_once is the right way to go here anyway).
