And why would the be necessary? If ev_prepare is soon enough, then you
obviously don't have the requirement of doing it immediately.

Well, foremost, it doesn't solve your stated problem at all.
If you just want a delayed unload, you can use ev_idle, or ev_timer. This
sounds like the likely fix to your usage - use the right watcher for the
job.
You can also implement your "immediately after a callback" idea by
providing your own EV_INVOKE implementation (when embedding libev), if you
really needed it (which is not the case by your own description).
