pushf and popf was used to add stream filter functions etc. They became 
unusable when
we removed the "middle man" process. Now all gen_tcp, gen_udp sockets 
are represented
by ports. The reason for the change was SPEED (traded for flexibility).

By implementing my old idea with port filters (.so/.dll modules that 
could be pushed on a port)
the pushf and popf could very well be implemented again ?
