I suspect some people may think that using #MongoDB is good idea. So I'll just drop here, how in #Gentoo we need to split the test suite of #PyMongo into 3 batches, and restart the server between them, because otherwise it crashes after performing too many queries. But I'm sure it's a great software in production.
