We noticed a problem while working on Web Storage. The broadcasting  
feature allows fork bombing. I personally couldn't think of any other  
features that allows such a thing.

Works against Gecko:

Works against WebKit:

Internet Explorer seems protected against this particular demo increasing  
only a slightly in memory usage (though a lot of I/O):

Should we really be introducing such a new feature (broadcasting) as part  
of sessionStorage/localStorage?
