Andrew,
   It really shouldn't be a shock since with Apple's trajectory
to migrate to clang, it becomes more sensible to have one system
wide unwinder etc in libSystem. Basically from darwin10 onward,
Apple will effectively be using an unwinder derived from gcc 4.2.1.

This gcj bug however seems to impact darwin9 as well which will use
the FSF libgcc so the problem doesn't seem to be specific to Apple's
unwinder in libSystem in darwin10.
