There's probably applications around that do IStorage_Release followed by
IStream_Release rather than the other way around.  If the app leaks memory on
Windows, the best we can do on Wine is to also leak memory.

It may have to do with the STGM_TRANSACTED flag that the storage is opened with.
 Perhaps OLE storage allows you to write to a stream in that case, but will
refuse to commit it back to the storage?

Unfortunately STGM_TRANSACTED is sorely missing in our OLE Storage implementation...
