Is the new API == current seed git?

Also, excuse my ignorance but is the new Gir file something specific for 
seed or improvements for the official GLib Gir-file? I'm not sure I 
entirely understand the system for all this gir-stuff, but I thought the 
files where generated from the actual libs somehow.. Also there was a 
gir-repository, is that the place to get them from or how does it work?

Wouldn't it work to just push the JSValueRef pointer as it is, and 
perhaps protect it from the GC while it's in the queue? Then one could 
just push whatever JS value to the queue and get it back as it was. But 
I'm surely missing something...
