Brian Barrett 44a516d966 * Clean up error checking in the MPI interface for MPI-2 onesided
* Implement fortran handle -> c handle tracking
* Remove some unneeded locking around free lists (the free list
  macros do their own locking)
* Try to be a bit more memory friendly with the w_mode setting /
  checking
