      [svn-r7416] Major improvement to RMA performance for long lists of operations, an immediate mode accumulate for single ints, store the MPID_Comm within the window, and added a basic performance instrumentation interface that was extensively used to improve the RMA performance (enabled with --enable-g=instr).  With these fixes, MPICH2 can run the one-sided version of the Graph500 benchmark at a respectable if not great rate

      [svn-r4062] 1) Modifying the datatype code to find the number of contig blocks in an instance of an MPI derived datatype - Since finding the real number of contig blocks is not easy we find a reasonable upper bound instead. This also fixes the case where the number of contig blocks was uninitialized for contiguous datatypes. Refer ticket #428 for details (2) Adding a test case, test1_dt.c, to test the fix - Review @ rross, thakur
