Yes.  If you control all the calls into JS_* you can do that. 
Basically, store some state associated with the JSContext if false got 
returned and JS_IsExceptionPending is false.  This should be doable with 
some sort of RAII helper that gets the jsapi result assigned into it, 
I'd thinkg.  Then clear the state if you decide to call 
JS_ClearPendingException or whatever API you're implementing that clears 
uncatchable exceptions.
