      Vagrant thought: with the fast file system in 4.2BSD, how fast could
a dumper that dumped file by file be made to run?  If tape I/O were overlapped
with file I/O (using one process to read the files and another to write
the tape, with a pipe between) and huge reads were performed, how much worse
would this be than reading raw file systems?  Maybe we can get rid of these
around-the-file-system dumpers.
