Object for monitoring a component, and later testing whether it's still valid.
Slightly obscure, this one, but it's used internally for making sure that
after some callbacks, a component hasn't been deleted. It's more reliable than
just using isValidComponent(), which can provide false-positives if a new
component is created at the same memory location as an old one.
