SharePoint's new fine grained permission model is really great, but I was a little disappointed to find out that you can't add permissions to an item without breaking its inheritance.
In NTFS security it is possible to do exactly that, as long as the change doesn't interrupt the original permissions. For example you can change someone's permissions from 'Modify' to 'Full Control' or add new user to the ACL, without breaking inheritance. This is possible Because the change doesn’t conflict with the old ACL.
Anyway it doesn’t work that way in SharePoint, so be aware of that.
