Tim's quite right.

I can't help but mention zc.async, which is now in a push to actually  
be used here at ZC.  It shouldn't be used--and perhaps can't be used-- 
by anybody other than us right now, I'd say (so that we're the ones  
dealing with breakage at this stage) but, as I said, I can't help  
myself:

lovely.remotetask is very similar in design to the Zope 2 zasync that  
we did some years back.  This new design is intended to address a lot  
of concerns with that design.

For now, I suggest you go with one of Tim's suggestions.  But hey,  
zc.async is/will be cool! ;-)
