There were some posts recently discussing whether it's poor style to put
import statements inside functions. I recently got reminded that there's
one very good reason to avoid it: Python has an import lock that blocks
more than one thread from executing import statements. Putting import
statements inside functions that might be called in a threaded
environment is asking for deadlock trouble.
