I actually considered just this morning adding annotations to Gecko's 
IDL to put the context-lost check in the binding...  It didn't seem like 
an obvious win given that we have existing hand-written code to check 
that, but if I were writing this from scratch it might have been.

I did look over it last week.  The steps are black-box identical to 
requiring a particular sequence of steps at the beginning of each of the 
IDL methods, which is how it's implemented in Gecko.
