I am attempting to write an application that requires some real time
control.  i.e. I need to prevent outside interrupts or context switches
from occuring at specific points in this code.  I have tried
setpriority() as a super user and have gotten nowhere.

Does 4.1.3 offer any other mechanisms for locking out tasks (including os
tasks) for limited periods of time?
