Re: remove all from a List

[Rick Riolo]

Here is how I check to see if the superiors List exists,
and if it does, re-start it with no members:

    if ( superiors )
        [superiors drop];
    superiors = [List create: xZone];

There may be a way to [superiors deleteAll] or some such, 
but I don't know how to do it, and haven't been
able to find it in the swarm/support/collections/*.h files.
