Does a process inherit its parent's RT rlimits?  I would expect them
to work that way.  If so, it should be enough to run your display or
window manager under set_rlimits.  Then, any app you started in that X
session would automatically inherit the ability to request RT
scheduling and mlock pages.

Also removes the issue of overly fine-grained control.  Anytime a user
with permission logged in, any app they ran will automatically work.

Of course, if rlimits are process specific and not inherited, then its
moot.  I thought about testing this last night, but went to sleep instead,
