Not really, no.  Once you remove it, even if there is nothing 
referencing it anymore (which may or may not be the case depending on 
what other code is running on the page), it still won't be destroyed 
until the next time garbage collection happens.  In the case of garbage 
collectors that can do different levels of collection (generational, 
etc), it won't be destroyed until whatever level is needed to destroy it 
happens.

In general, depending on finalizers to release resources (which is 
what's happening here) is not really a workable setup.  Maybe we need an 
api to explicitly release the data on an audio/video tag?
