I suspect this is a garbage collection issue rather than an outright leak (though I could be wrong).  A good test might be the "granular synthesis" demo since it continually generates large numbers of audio sources:
http://chromium.googlecode.com/svn/trunk/samples/audio/granular.html

Once each source (representing a grain) is finished playing then it should be ready to be garbage collected, though large numbers of these sources could build up if collection does not happen frequently.

It might be possible to take a test case like this, then add a "Garbage Collection" button to force garbage collection to see if this helps reduce memory.

If it is a garbage-collection related, then perhaps there's a way to indicate to JSC that these sources need to be collected earlier than they are.
