Twas brillig at 12:52:54 13.12.2010 UTC-05 when ajax at redhat.com did gyre and gimble:

 AJ> Instead of actually processing input in the handler, raise just enough
 AJ> of a dispatch exception to bomb out of request processing and handle input
 AJ> instead.  This gets us back to exactly two input processing methods:

 AJ> - input thread
 AJ> - main loop dispatch

 AJ> where the SIGIO handler is merely an optimization for the second case.
