New submission from Eric Snow <ericsnowcurrently@gmail.com>:
When looking up a frozen modules, we loop over the array of frozen modules until we find a match (or don't). See find_frozen() in Python/import.c. The frozen importer sits right after the builtin importer and right before the file-based importer. This means the import system does that frozen module lookup every time import happens (where it isn't a builtin module), even if it's a source module.
