Looks like Seam is doing most of the resource lookup work based on URLs.
And with no URL/VFS/resource/etc caching, VFS needs to re-create the whole structure over and over again,
hence unpacking nested stuff, re-initializing it on every unpack.
This should go away with better Seam+MC+AS integration.
But yeah, meanwhile I'll have a look what can be done.
