Can you call JS_AddRoot multiple times for an object?

And does every JS_AddRoot need to be matched with JS_RemoveRoot?  For
example, if I do:

JS_AddRoot(cx, &pObj);

.....

JS_AddRoot(cx, &pObj);

.....

JS_RemoveRoot(cx, &pObj);

Is the JSObject pointed to by pObj still rooted and protected from being
gc'd (since I've called add twice, and remove only once)?  Or does is it the
case that once JS_RemoveRoot is called, that's it, the obj is unrooted, and
gc'able?

Thanks,
Ed
