I've added a lot of debug code to the module to try various things. Maybe you can help make sense of the results?

First off, a very strange thing: I put a warn before and after $callback->() in synchronize(). On the very first hit to that code in a run it always takes 30+ secs to execute a dummy callback!!? The output is below. The long number is time(). The $VAR output is Dumper($callback). 

1291361165 zb before cb
$VAR1 = sub { "DUMMY" };
1291361200 zc after cb, before wait

After that first hit all subsequent $callback->() (which are also all DUMMY) take 0 secs! This doesn't make any sense to me at all. How can a dummy call take 30 secs?

I've tried adding load to the events (globally). Right before the $load_lock=... in synchronize() I added a Dumper($events) to confirm it's there: 

$VAR1 = [
          'load',
          'DOMFrameContentLoaded',
          'DOMContentLoaded',
          'error',
          'abort',
          'stop'
        ];

I also tried it with just load (no other events). In all cases _wait_while_busy loops until my 20sec timer stops it, so no change there. Any other events I can wait on?

I also Dumper'd the $element in the for $element loop of _wait_while_busy, but that returns some massive structures that don't mean much to me (you're losing me with all the javascript code). However, if tidbits could help debug, I can post here as required.
