C<ev_loop_new>. Yes, you have to call this on every allocated event loop
after fork, and how you do this is entirely your own problem.
=item unsigned int ev_loop_count (loop)
Returns the count of loop iterations for the loop, which is identical to
the number of times libev did poll for new events. It starts at C<0> and
happily wraps around with enough iterations.
This value can sometimes be useful as a generation counter of sorts (it
"ticks" the number of loop iterations), as it roughly corresponds with
C<ev_prepare> and C<ev_check> calls.
=item unsigned int ev_backend (loop)
Returns one of the C<EVBACKEND_*> flags indicating the event backend in
