Pull #442

travis-ci

Explicitly close stores during tests.

This is especially troublesome on 32-bit systems with LMDB, as opening
an LMDB store maps 2**28 blocks, and letting the gc clean them up can
cause excess memory pressure. Eventually, this results in LMDB tests
failing to open a store because it can't find a 2**28 block to mmap.
