Or we could build two versions of ObjectInputStream, with and without
instrumentation. The normal one goes in libgcj.so and the instrumented one
goes in ser-dump.so, so under Linux at least, you just run MyProgram like
so....
$ LD_PRELOAD=ser-dump.so MyProgram
...to get the new behaviour with zero overhead otherwise.
