This is a mock for L{open}. It keeps track of opened files so extra
descriptors can be returned from the mock for L{os.listdir} when used on
one of the list-of-filedescriptors directories.
A L{FakeFile} is returned which can be closed to remove the new
descriptor from the open list.

Check that the identity of _listOpenFDs changes after running
_listOpenFDs the first time, but not after the second time it's run.
In other words, check that the monkey patching actually works.
