There are two obvious ways I could see this happening.

First, a device driver (other than a BASEDEV) is allowed to access files on
file systems mounted so far during its initialization.  This is intended to
allow a device driver to load disk configuration files if necessary.  If a
driver opened a file and failed to close it during initialization, then the
file handle would be permanently orphaned.  Some device drivers do this
deliberately, notably the unregistered version of SIO.SYS, which opens and
locks a file called "\SIO DT" (where the space is actually a hex
0xFF character).

Second, a remote IFS can have funny effects on the FS router in OS/2 when
it claims all unused drive letters, as it is entitled to do.
