I am more interested in making kernel symbols and their values available
to programs. For example I currently need the value of
"delay_at_last_interrupt" a wonderful value that the time.c keeps.
I assume that I can clip code from ksymoops to fetch the symbol address
and hopefully its value. Since this thing changes each 10ms I need to
get it in a hurry.
