Yes and no. We do something similar to this for the module loader and subscript loader, but only for the entire compiled source, not for individual functions, and without any kind of lazy compilation.
True.
For <script> tags in XUL documents, we only use a bytecode cache for inline scripts. Other scripts are compiled off-thread from source, using the ordinary script loader logic. Or, at least, that's my understanding after investigating whether we could use the script precompiler for them, to improve first paint time.
Hmm. I guess we still cache the compiled script in the nsXULPrototypeCache but no longer do XDR for out-of-line <script>s? That's certainly a change from the last time I looked at that code... We used to do XDR there.
Doing the per-function thing might make sense if (as I expect) most of our chrome code is cold...
