I don't use PEAK events and Twisted together for anything at the 
moment, but this is a Very Bad Thing to propose... it basically turns 
any Twisted reactor into a polling reactor, the performance will suck, 
and it won't integrate very nicely with some GUI frameworks (especially 
OS X, because iterate basically starts up the runloop and shuts it down 
with a callLater.. it's only there because the tests use iterate all 
over the place instead of run/stop).
