Yeah :-(

If I were you I'd have some sort of job-server (mod_perl
would be my  
recommendation) that you call to entirely separately.

So you return YIELD from a hook and it suspends the plugin
stack (not  
the execution stack as that would require core perl support
for  
continuations). You then have to have some kind of event
fired from  
the event loop - either a timeout or a socket event or
something that  
calls $client->finish_continuation - that then picks up
at the NEXT  
registered hook/plugin. So if you want that to be within
your own  
plugin you need to register multiple hooks for the same
phase. See  
plugins/aio for examples.

Note: "return CONTINUATION" is used in the
examples but that's about  
to be deprecated in favour of "return YIELD" which
is more  
syntactically correct.

I presume this is short term until the easy to use and
implement job server
arrives?
