Execute code immediately after watcher callback function returns

thank you for maintaining libev, it is a great piece of software, and I've
used it in numerous applications already.
Now to my question:
I have a module loaded that will be woken up by a watcher, and the module is
supposed to signal itself to the program, when it can be unloaded. For obvious
reasons, I cannot unload the module directly from the module itself or the
callstack gets corrupted.
So, I'd like to "inject" the execution of code immediately after the callback
function from the watcher has returned.
I had two possibilities in mind: Add an ev_prepare watcher that unloads the
module before next loop interation, or add an idle watcher with high priority
from the module itself (does this work at all?).
However, the first possibility does not unload the module immediately, but
only when all other watchers have finished processing, and the second
possibility seems rather hackish to me.
That's why I'd like your opinion on this. Please add me to the CC, because I'm
not subscribed to the mailing list.
All the best,
