    [svn-r10423] Added passive target immediate locking · 5109ab1b
    James Dinan authored
    When enabled, this mode of operation immediately requests the lock when
    MPI_Win_lock is called.  Currently, this is enabled by setting the
    MPICH_RMA_LOCK_IMMED environment variable.  In the future, we can also make
    this mode of operation available though an info/assert.  This capability is
    needed to implement MPI-3's flush operations.
