+=item unsigned int ev_loop_depth (loop)
+
+Returns the number of times C<ev_loop> was entered minus the number of
+times C<ev_loop> was exited, in other words, the recursion depth.
+
+Outside C<ev_loop>, this number is zero. In a callback, this number is
+C<1>, unless C<ev_loop> was invoked recursively (or from another thread),
+in which case it is higher.
+
+Leaving C<ev_loop> abnormally (setjmp/longjmp, cancelling the thread
