Still the same assert failure with that chunk of code.  I blindly
tried a few other variants on the theme as well.  If I move the assert
after the assignment, e.g.:

    if (j++ & 1)
      {
        w2 = w2->next;
        assert (("libev: io watcher list contains a loop", w != w2));
      }

Then it works.  If I change j++ to ++j in the above, it still works.

Other obvious variations all produce assert failures (moving assert
back above the assignment, or outside of the if-branch completely).
