29658	Use unittest.addCleanup to unregister lookups.	Mads Jensen	nobody	"There are some places in the test suite that follow this pattern:

{{{
try:
   CharField.register_lookup(Length)
   # some test code
finally:
   CharField._unregister_lookup(Length)
}}}

It'd be better to use `unittest.addCleanup` to handle this stuff."	Cleanup/optimization	new	Core (Other)	dev	Normal				Unreviewed	0	0	0	0	1	0
