Comment (by joemcgill):

 Replying to [comment:13 coreyw]:
 > @joemcgill It doesn't appear that resetting the globals would help. It
 seems that calls to `get_stylesheet_directory()` return an invalid path if
 called before a certain point (when the theme is setup perhaps).

 Interesting. Perhaps the answer would be to make sure we don't memoize
 these paths until the `plugins_loaded` or `setup_theme` action has fired,
 to ensure that early calls to those functions don't result in stale
 values?
