on the first paragraph of the new uWSGI docs page about reloads:

"When running with the master process mode, the uWSGI server can be
gracefully restarted without closing the main sockets"

then it goes to explain how to reload code. without breaking any
request in the process.

in short, since Django loads all python code at startup, you can
replace the code (ideally using a VCS) while it keeps running. after
that, you send the SIGHUP signal to make uWSGI reload the app on each
worker as it finishes current requests.
