An embodiment of a method of performing a kernel level task upon initial
execution of a child process at a user level begins with setting an
instruction pointer for an initial child process instruction to an
instruction to enter a kernel level. The method continues with beginning
the child process which places a return value in a register for the child
process and which causes the child process to enter the kernel level. The
method concludes with executing a system call having a system call number
of the return value. The system call comprises the kernel level task.
