[p4] Very old pending change lists

[Jamison, Shawn]

Howdy everyone! 

I was trolling through the Pending change lists and found some very old
change list dating from 2000 and 2001.

Some of the old Change lists are in the 2000 range when we are currently
working on 254000+ numbers.

Why doesn't deleting the client spec and user delete any associated
pending change lists?  

Is it safe to just delete these assuming they are empty?



Thanks in advance for your help.
