No, not completely.  There are still plenty of bugs.  AWT is in active

Where do you see this?  I don't see a field named native_state
anywhere.  There is "native_state_table", but it is just an ordinary C
global, not a field.

Maybe this code has changed since 0.06; I didn't look.

The new standard Gtk thread code uses portable locking -- it uses JNI
calls to do its work.  This should work for any threading system.
Offhand I don't know whether this has been made the default yet; you'd
have to read the source to see.
