GAMMA seems to be stable these days. We have run 
succesfully with a version two versions before 
the current one. Before that there were indeed 
problems but they seem to have been fixed.

Could be interesting to ask the author of GAMMA to 
see why he didn't use netpoll/mmap_ring (no idea 
what they are I'm afraid) and whether it would be 

I'd be certainly interested in a protocol which is 
less intrusive than GAMMA.
