You don't have to worry about getting swapped out like that.
A preocess in kernel mode on Unix may only be swapped out
when it does not have the CPU, and a process may not lose
the CPU to another process unless it wants to ( i.e., calls
sleep() or swtch() ).  Thus, one does not have to worry about
an interrupt causing one to get swapped while in kernel mode.
