Re: MasonHQ node caching, and other bugs

I'm afraid that I was a little too optimistic too soon. The old node 
caching still seems too happen. I just didn't discover it. If I update the 
same page rapidly then in the browser it appears as if each update takes 
place. But if I wait a minute or two and edit again, then some random 
older page will show up in the edit form. The revision history for a page 
is interesting:

History for 'SandBox'

Same version number is used several times, and not in order.

Now, with this version number mismatch, when I click on a "diff from 1.66 
link" I get Internal Server Error and this message in error log:

How can I find out why the node caching occurs? Or is it the node version 
number that is cached?
