er.  This implies the association between the 'async-argument' and
the CUDA stream will be maintained for the lifetime of the program.
However, this association can be changed through the use of the library
function 'acc_set_cuda_stream'.  When the function 'acc_set_cuda_stream'
is called, the CUDA stream that was originally associated with the
'async' clause will be destroyed.  Caution should be taken when changing
the association as subsequent references to the 'async-argument' refer
to a different CUDA stream.
