Yes, that too is possible: abstract the application's event loop and
export it to libraries.  That is complicated and only sightly more
portable than just exporting file descriptor lists from the library to
the app.

Indeed.

I'm not sure we'll ever reach consensus on a single async GSS API.  We
might have to do more than one, or none at all.
