Comment (by gcc):
+1. This just bit us as well.
I think if flush is going to invalidate caches (which it appears to do),
then it should be sending a signal that allows holders of caches to
respond appropriately. So something like this in flush.py:
{{{
for app in set(all_models):
models.signals.post_flush.send(sender=app, app=app,
created_models=created_models, verbosity=verbosity,
interactive=interactive, db=db)
emit_post_sync_signal(set(all_models), verbosity, interactive, db)
}}}
Assuming a new signal `flush` which ContentTypeManager listens for, and
then flushes its cache.
