still, we have had some incompatibilites with PEAK upgrades, and when 
our application kernel became stable enough, we decided to freeze all 
external dependencies, including PEAK.

yes, that's what we needed.  we made our own reactor (heir of 
UntwistedReactor) with the following additions:

* exit MainLoop when there are no readers, writers or laters,

* additional readers for TCP exceptions (third list in select() 
parameters), to receive out-of-band data.

* ability to remove sheduled procedures from the laters list
