I did something like that to ensure that NSApp is initialised in
the main thread.  I think it's probably important to know that the
drawing thread is the same as the main thread.

I don't think there is much point recording the actual thread ...
sure we could then test to see if the current thread is the one we
can draw in, but we can effectively do that by testing to see if the
current graphics context (GSCurrentContext()) is nil anyway.
