Thats great but what does one execution mean to the
kernel. It will be executed with a fraction of time 
and why  is it suposed to lock the kernel.
And if it locks by any chance why do we need to lock
the kernel (I mean in which scenario do we need to
lock the kernel).Is it becuase we need a time out for
any of our modules or ... what else

First of all is it meaningfull in the case of a single
processor or is it useful only in the case of SMP.

Thanks
