Today will be a busy real life day.

The main thing when I reach it will be exception handlers, need to preserve
that state.

Another main thing will be garbage collection, a thread safe and fast way to
indicate that objects are no longer being used.

Well, exception states are always known. However for some virtual machine
thrown exceptions like say NullPointerException or other errors like out of
memory, such states will not be known. I believe for normal exceptions the
state of execution is known while for random VM errors it is not guaranteed
that values will have certain values since it could happen anywhere. I would
have to look that up. Perhaps for object garbage collection I can have a
method cleanup which cleans up any assigned register sets at the end of a
method call although that could be an issue on long loops. I could collect on
object set when it is done in a register.
