What do you mean "reinitialized many many times"?

Before this API, all DOM windows were initialized before each document
load via JS_InitStandardClasses.  That creates *all* of the standard
class objects (Date, parseInt, RegExp, ...).  With
JS_ResolveStandardClass hooked up via the DOM's window class resolve
hook, only those that *a particular document* uses from script are
created, and only for those windows that load documents with scripts.

Are you sure you're understanding what you see in the debugger?  If you
do see some kind of bug where for a given window, for a single document
that uses, say, the Date constructor, js_InitDateClass is called more
than once, then please file a bug.
