NAME
drum - paging device
SYNOPSIS
This file refers to the paging device in use by the system. This may
actually be a subdevice of one of the disk drivers, but in a system
with paging spread across multiple disk drives or interleaved will be
an indirect driver.
FILES

BUGS
Reads from the drum are not allowed across the interleaving boundaries.
Since these only occur every .5Mbytes or so, and since the system never
allocates blocks across the boundary, this is usually not a problem.
