OK, I'll implement it this way and upload some patches shortly.
One other thing which, looking at the code, we maybe should
consider: the documentation for clearScriptLinks() [in
for Object class, anyway] says it returns "0 if some internal
problem occurred or 1 if successful", which doesn't seem
very helpful.  I hate exceptions as much as the next guy
(well, hate *getting* them, anyway), but at least they're
diagnostic so I can try to figure out why it failed.
