[Asterisk-Dev] rewriting asterisk as a state machine?

[Roy Sigurd Karlsbakk]

hi

in current asterisk gateway setups, a set of 20 active channels 
generates something like 3500 context switches per second, giving a 
170-200 context switches per channel per second. This is an awful 
lot...

Would it be possible to rewrite asterisk so as each channel's data 
read/write would be in common threads with a select() or so? what would 
this take? this really would decrease the overhead on busy systems....
