undo-limit and Emacs scability

Hi all,

I would like to increase my Emacs' undo-limit from 80k to something more reasonable, since I do lose undo history sometimes.  What are some considerations I should keep in mind?

How should I change undo-strong-limit in relation to my new setting?

My system has 4 GB of memory.  If I set my undo-limit to 2 MB per buffer, and I often have 20 or more buffers open.  Will Emacs be good at managing that amount of allocated memory?
