The new JS HashTable is easier to use, easier to understand, and, most importantly, we are building tools to make the new hash tables work well with a moving GC. The JSDHashTables in XPConnect are the last in the tree and it's time for them to go.

This is my first patch against XPConnect, so I've limited myself ot a single table: the JSObject2JSObjectMap used for waivers.  The diffstat for this patch is:

I think it's a good start.

Nit: Braces around the for loop's body.
