I found this or something similar when upgrading a i386 1.1 machine to
1.3 at the weekend.

  $ (cd /some/place; tar cf - .) | tar xpvf -
  tar: can't write to - : Broken pipe

In this case the writing side is writing a bunch of \0's that the
reading side doesn't want, so SIGPIPE might be entirely correct.
All the data was transferred correctly.

I can't reproduce the problem in -current, however my -current machine
runs diskless and is using UVM and PMAP_NEW so there are some
differences.
