hdf5/test/btree2.c
Quincey Koziol 7316f0e7e7 [svn-r9995] Purpose: 
New feature & bug fix

Description:
    Allow root node to split, forming a level 2 B-tree

    Fix error where wrong record was being copied up to parent node for a 2
node redistribution on the "right" side of the B-tree.

Platforms tested:
    FreeBSD 4.11 (sleipnir) w/parallel
    Solaris 2.9 (shanti)
