I have not been able to reproduce this so far, but I have found that
if the file is large, say 10000 lines, it takes a few seconds.

The other problem I found is that if I run `python-fix-imports'
without saving the buffer, I get the following error:

python exited with status 1

This occurs because isort cannot read the lock file (symbolic link)
such as ".#foo.py", which is created before the modified buffer is
saved.  Although I don't think this has anything to do with the
non-response issue.
