Is there any reason that you can't ensure your program variable's

my understanding is that cache coherency is taken care of at the
hardware level and that only very low-level stuff like kernel
drivers and such would need to worry about it.
this particular app would fall under the "multimedia" umbrella...
video playback and such, but nothing kernel-deep.
knowing this, is it possible that pointer assignment will be
effectively atomic even across multiple cores?
thanks.
