insure bit-wise reproducibility of binaries. Thanks to Alastair McKinstry
for help in fixing this problem.

of MPI_ABORT that could lead to job hangs. Thanks to Christof Koehler for
reporting.

in a job. Thanks to Noel Rycroft for reporting this problem
- Plug some memory leaks in MPI_WIN_FREE discovered using Valgrind. Thanks
to Joseph Schuchart for reporting.

Thanks to Yvan Fournier for reporting.
- Fix a problem with MPI_FILE_DELETE returning MPI_SUCCESS when
deleting a non-existent file. Thanks to Wei-keng Liao for reporting.
- Fix a problem with MPI_IMPROBE that could lead to hangs in subsequent MPI
point to point or collective calls. Thanks to Chris Pattison for reporting.
