The next thing is to get -pg -static working.  That means that the
dynamic linking emulation needs to work like it does in that Kaffe
profiling example I posted a while ago..  I'll probably have something
to report on that soon.  (Profiling code that uses dynamic linking is
hard to do in a portable way..)

>From that, we'll either find a bottleneck in libgcj itself or perhaps
a more expensive garbage collection problem.  Then there are the
Objective-C <-> Java lookup conversions.  With gcj, we can treat everything
as a C object, so these lookups can be eliminated in favor of extra
ivars, thus eliminating the lookups.

So we should be seeing performance improvements..
