cpio reporting too many 'blocks'

In a CURRENT snapshot built at:
FreeBSD 8.0-CURRENT #0: Mon Sep  1 03:13:59 EEST 2008

bsdcpio is reporting _very_ large block counts:

  keramida_at_kobe:/ws/bsd/doc$ find * | cpio -p -dmu /hg/doc/bsd-import
  757935406 blocks
  keramida_at_kobe:/ws/bsd/doc$ du -sh .
   24M    .
  keramida_at_kobe:/ws/bsd/doc$ env | fgrep BLOCK
  BLOCKSIZE=K

I haven't tried building cpio from earlier versions yet, because an
mpsafetty test patch is building as I type this.  The last few commits
seem related though:

  MfP4: Verify correct interaction with umask:  Add another
  file with different permissions and set a non-zero umask
  during the actual copy tests.  The extra entry increases
  the size of the test archives of course, so adjust the
  expected sizes.

  Update the total archive byte counters when writing entries to disk using
  archive_write_disk.
  Update cpio to use this to emit block counts in -p mode.
  Update cpio tests to verify these block counts.

Is anyone else seeing similar/bogus cpio block counts?
