I think it's two rather orthogonal things - libev doesn't use any kind of
semaphores internally, so will hardly collide.

I guess you cna safely treta it like many other thing not mentioned in the
documentation, such as "does it work with prime numbers", "does it work with
my toaster", "will it interfere with iceweasel on the same system".
You typically run into problems if you mix multiple event libraries, as
most event sources under unix are single-use points (signals for example),
but since libev doesn't use semaphores itself, you are safe.
