/* HACK: stream file object seems to get deleted at some point
* leading to use after free when installing ReactOS on
* BtrFS.
* Workaround: leak a handle to the fileobject
* XXX: Could be improved by storing it somewhere and releasing it
* on dismount. Or even by referencing again the file object.
