23372	Prevent loaddata from disabling and enabling constraints when no fixtures are found	Michael Manfre	nobody	"On my primary development system (Intel i7 quad core with SSD drives), it takes nearly 20 minutes to get from executing {{{runtests.py}}} to the start of the first test. Most of the time (~18 minutes) is spent on the ""loaddata"" call_command in the migrate command's sync_apps method.
