Comment:

 I tried increasing the content size (up to the limit of my patience for
 running the test) but it didn't increase the size of the hash tree past
 the 4000 bytes it would take to push it out of the initial cache fill.
 What's an estimate of the file size this would require?

 I added a function to MDMFSlotReadProxy to clear its cache, as well as one
 to clear all the proxies in a servermap. The test_corrupt_all calls this
 function before attempting to retrieve data. All the tests pass once again
