R. David Murray added the comment:
This situation is warned about explicitly in the threading docs (https://docs.python.org/2/library/threading.html#importing-in-threaded-code). The import deadlock is fixed in python3, but it is still a really bad idea to launch threads on module import.
What isn't obvious, of course, is that calling encode for the first time for a given encoding does an implicit import of the relevant encoding. I don't think encodings is the only stdlib module that does implicit imports, but it is probably the most used case. Maybe it is worth adding a warning to that section of the 2.7 docs about implicit imports in general and encode/decode in particular?
