On the test machine leave the packages in the cache. Then use a 
separate script to extract all packages from the cache and put 
them in a new repository. Have the critical machine only pick up 
packages from your local repository.  Someone on this list posted 
a script which can be used to keep your local repository trimmed 
to only the latest versions (repomanage.py). With this setup it 
becomes a trivial task to delay files going into your repository 
for a few days.
