27790	Investigate increased memory usage in tests when calling migrate without available_apps set	Tim Graham	nobody	"91023d79ec70df9289271e63a67675ee51e7dea8 increased memory usage of the test suite. I've created a [https://github.com/django/django/pull/7972 PR] to revert it but the root cause should be investigated.

I added these lines at the end of `runtests.py` to measure memory usage (may be a naive solution):
{{{
import resource
print(resource.getrusage(resource.RUSAGE_SELF).ru_maxrss / 1000)
}}}"	Cleanup/optimization	new	Migrations	dev	Normal				Accepted	0	0	0	0	0	0
