Comment (by lloydbudd):

 +1 to removing the call validate_current_theme() from wp-settings.php

 file_exists can fails (returns false) when there is file contention. I've
 been working with a friend who supports a number of busy blogs and on two
 different hosting environments he has issue with regular resets -- and by
 regular, I don't mean I can see a pattern to the time interval, sometimes
 it can be a few minutes a part, sometimes a few hours.

 validate_current_theme with its 2 file checks is useful for basic sanity
 when going to the Presentation tab, and it would be great if it did more
 checking, but a synchronous wp_file_exists on every load of WP seems
 awkward, and won't detect most problems with a theme.
