Will not happen - here is a non-exhaustive list why:
- if all you need is the number of invocations, you can implement a counter
using atomics. likewise if you need a queue of sorts. In many cases
applications that do nontrivial things _already_ implement a counter or a
queue for their own purposes, in which case libev's multiple invocations
would be just unnecessary overhead that is not needed ever in practise,
but punishes everybody because libev has to implement it's own counter
or queue internally.
- it would be inconsistent w.r.t. any other watcher type, all of which
combine multiple events into a single callback, which is generally
the most efficient way to implement it.
