I'm wondering if or when we can expect the MoreBacktrace stuff from the
MoreIsBetter sample code to be ported to i386?

It might be better at this point to use dwarf2 eh tables to get a backtrace
than it is from x86's stack frame because if you don't have a frame pointer,
stack frames are "messed" up.

Mac OS X doesn't support DWARF yet and the compiler doesn't omit frame pointers (though you can write asm functions which omit them), so for now regular backtracing code will work fine in nearly all cases. Unfortunately, MoreBacktrace should handle all cases, not nearly all, so it'll take a little bit longer before it's ready.
