Michael,

I detect a disconnect.

Victor needs some way to be able to set the real time features of Linux;
this is certainly desirable in various audio, voip and similar
applications.

Victor has been using the facilities in limits.conf to enable particular
user's accounts to do this under linux.

It seems reasonable to me that Rainbow should provide a way for a bundle
to declare such needs....
