I believe we should stop maintaining an autoreloader as soon as possible.
Django’s autoreloader is annoyingly slow, highly inefficient, moderately
well designed, and a gigantic pain to maintain. I’m more scared of
`django.utils.autoreload` than of `django.db.models.related` before it was
cleaned up.
I wish one day someone will take the time to write a good autoreloading
dev server based on watchman. This would solve the problem discussed here
because watchman watches all files in the current directory. The correct
way to do this is to throw away the current design and start from scratch.
Watchman is smart enough to wait until you’ve finished a git operation to
trigger a reload. Once such polished tech has become available, trying to
compete with a thread that checks the mtime of all known files every
second isn’t funny anymore. In fact it’s just sad.

The [https://groups.google.com/d/topic/django-
developers/voXNIDdDcpU/discussion Future of the development server's auto-
reloading thread] has some ideas about this.
