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.
