That's the whole point of this test. The observed behavior is that you can pass a
filename to MsiRecordSetStream, successfully delete the file, and keep on using the
stream.

We currently implement MsiRecordSetStream by creating an in-memory copy of the
stream. As Robert noticed, this will fail if the stream is too large.

The idea is to move to an implementation on top of a file handle, but it should
still allow DeleteFile to succeed while the file is in use.
