# MTDEALLOCATE -- Deallocate a previously allocated tape drive. To deallocate
# a drive we try to rewind (any errors, such as drive offline, will result in a
# warning message), and then delete the lockfile. We do not call up the OS to
# deallocate the drive; that is done at a higher level, usually XDEALLOCATE
# (in etc$xalloc.x).
