[development] Deleting Cached Permissions

[sysop at scbbs.com]

Yes, that would be perfect.  The problem is that this functionality is  
currently not in user_access().

I looked at the php docs and see that this is possible, but the only  
way to implement it in user_access() would be to modify the  
user.module -- which I'm trying to avoid.

Quoting Moshe Weitzman <weitzman at tejasa.com>:
