[svn-r7122] Purpose:
Code cleanup/Feature removal
Description:
Remove "round robin" writing of metadata in MPI VFDs (and a couple of other
places). This never really worked the way I hoped it would and it causes
problems on certain machines.
Platforms tested:
FreeBSD 4.8 (sleipnir) w/parallel
Too small for triple check.
