Well, since every GstThread has a thread object, you can simply check
whether we (emission thread) is the same as the parent thread and handle
it, no?

I'd think that you would want hooks in bin and scheduler for this, and
simply call these hooks to let that handle what thread to emit the
signal too. From thread, send to parent bin thread (or, if no parent,
main thread). From pipeline/bin, send out directly. From element, send
to scheduler (which sends it from correct context for the (co)thread
this element runs in to its parent).

Bit simple, but you get the idea...

But in general: really cool(tm)!
