[svn-r12084] Purpose:
Code checkpoint Description: The fractal heap code is reasonably stable and is passing all its current tests, so checkpoint everything with CVS. Also, add "statistics" module for v2 B-trees code, which is only a stub right now. Platforms tested: FreeBSD 4.11 (sleipnir) Mac OSX (amazon) Linux 2.4 (chicago)
