Three reasons: Performance, performance, and performance! By
the way, is tracing inherited by child processes?
Counting the syscalls isn't a problem -- it's easy to see what
to do in "arch/i386/.../entry.S". Allocating the buffer in
appropriate read/write memory, ensuring it is cleared (does that
happen automatically?) on bootup, learning the interface to make a new
"/proc" file -- those are the tasks.
