Testing memory usage with MongoGridFS::storeFile()

Configuration

For our tests, we used random input data created cat /dev/urandom > random.txt.

Set the URI, database, and GridFS collection names accordingly. Additionally, decide if the GridFS collection should be dropped before inserting any data.

The number of iterations can be customized. Based on the results, there were modest increases to peak memory on successive iterations. Real memory usage tended to drop with each new iteration and climb again.

By default, the driver uses a chunk size of 255 * 1024 (i.e. 255K). This default seems to leak memory (at least until the file insert completes). Increasing the chunk size even just a bit 256K has vastly better results.
