Ah I see.

Yeah grep "CREATE(" *.c | wc -l says I've got 62 instances to look at,
although after giving it some thought, I'm going to have to also change
all strdup's if I want to change all the free's. It's either that, or
figure out which fre's match the creates and selectively change those to
the new FREE macro.

I'm using 2 checks, one an immediate check of one pointer, to make sure
it's still valid and hasn't been over written, and the second a check of
all pointers. I'll probably call that once per game loop, depending on
how long it takes.

That may be ok for logging, but passing filename and function to the
manager wouldn't be very useful for determining memory type. I'll have to
do it all by hand, or at least in the areas where I care.
