Brian Barrett 79ad6d983e - The ptmalloc2 memory manager component is now by default built as
a standalone library named libopenmpi-malloc.  Users wanting to
  use leave_pinned with ptmalloc2 will now need to link the library
  into their application explicitly.  All other users will use the
  libc-provided allocator instead of Open MPI's ptmalloc2.  This change
  may be overriden with the configure option enable-ptmalloc2-internal
- The leave_pinned options will now default to using mallopt on
  Linux in the cases where ptmalloc2 was not linked in.  mallopt
  will also only be available if munmap can be intercepted (the
  default whenever Open MPI is not compiled with --without-memory-
  manager.
- Open MPI will now complain and refuse to use leave_pinned if
  no memory intercept / mallopt option is available.

[all mem leaks]
The following memory locations were allocated via MPI_ALLOC_MEM but
not freed via MPI_FREE_MEM before invoking MPI_FINALIZE:
Process ID: %s
Hostname: %s

[some mem leaks]
The following memory locations were allocated via MPI_ALLOC_MEM but
not freed via MPI_FREE_MEM before invoking MPI_FINALIZE:
Process ID: %s
Hostname: %s
PID: %d
%s
%d additional leak%s recorded but %s not displayed here. Set the MCA
parameter mpi_show_mpi_alloc_mem_leaks to a larger number to see that
many leaks, or set it to a negative number to see all leaks.
[leave pinned failed]
Process %s on host %s attempted to use the leave pinned
feature, but no memory registration hooks were found. To solve this
problem, either link in the libopenmpi-malloc library or (on Linux)
do not set the MCA parameter base_disable_mallopt.
