30420	Do not reload runserver during debugging / request processing	Daniel Hahler	Artyom Kotovskiy	"The server should not be restarted while debugging (`pdb.set_trace()`).

Use case:

1. `pdb.set_trace` in the code
2. trigger web request
3. start debugging / messing around, maybe even use `edit` (via pdbpp) to edit files
4. save something being watched

This ends up in garbarge on the screen, and the server process/thread getting killed.

This could be achieved using a thread lock.

See https://github.com/pallets/werkzeug/pull/1525/files for an example."	Bug	assigned	Core (Management commands)	dev	Normal			Florian Apolloner	Accepted	0	0	0	0	0	0
