I can see a use for doing per-object debug levels, but I'd rather not add
the overhead to every object, especially when it would be used by a small
minority of the populace.

Such a flag could easily be placed in the subsystem-specific object, and
accessed through the logging/debugging wrappers.

It would be nice. Unfortunately, it's only a nifty pipe-dream at the
moment, unless some lucky volunteer would like to step forward. ;)
