Careful! Pipes are actually I/O on any implementation of UNIX (TM) that I have
seen. The way these work is to use disk blocks as buffer space.
That is that although the use of a pipe  will greatly reduce the amount
of disk space used, it does not avoid the use of the filesystem altogether,
and you may still run out of disk space if space is really tight.

Unless someone has changed the system configuration, the root disk partition
is also used as the PIPEDEV (which defines what device is used to buffer pipes)
The "/etc/sysdef" command can be used to verify the PIPEDEV.
(It can also be found in the /etc/system file)
