 Howdy,

 Now, I am trying to estimate what the cost of a system call, To be more accurate,
how many instructions have to be executed.
 So many high-perf communication systems are implemented in user space, just to bypass
all kinds of system calls. Could we make a thin system-call-layer to ease the life of 
guys in these efforts?
 
 TIA.

  I18n of linux is necessary now. I want to contribute to it.
