unexpected multi-threaded dev server!

[trey.smith@…]

On installing Django 1.4 I was surprised to find that:

• The dev server now has a multi-threaded mode (great)
• The new multi-threaded mode is used by default (surprisingly aggressive)
• The release notes don't mention the new feature at all! (really?!)

The new multi-thread mode caused some problems for me with threads trying to use shared database connections which I will detail in another ticket. The thing I am pointing out here is that multi-threading is a big change, likely to cause many issues, and it took me totally by surprise.

I think the release notes should mention it and detail how to use --nothread to turn it off in case of problems.

Thanks!

Er, --nothread should be --nothreading

This was reported again in #18126. A quote from that ticket (by onyxfish):

I stumbled across the new --nothreading option. It says to read more in the release notes, but this isn't mentioned in the release notes. This really tripped me
up when a threading bug appeared in development code where I did not think such a thing was possible.

I am not sure where this should be patched: 1.4 branch, trunk or both?

I'd say "both".

Suggestion for the docs.
