[svn-r12638] Description:
Split edge nodes in the tree with a 1->2 node split, instead of a 2->3 node split, which creates a more dense tree when a pattern of record insertions occurs (because it leaves behind full nodes instead of 2/3 full nodes). Tested: FreeBSD/32 4.11 (sleipnir) Linux/64 2.4 (mir) Linux/32 2.4 (heping) Solaris/64 2.9 (shanti)
