Ah, in the static case, yes. But in our case cpusets would always be
dynamically allocated.
It's not the size of the array in the cpuset struct that matters --
it's the size of the struct.
Are there any global constants akin to MPI_COMM_WORLD? (e.g., an empty
cpuset, or a full cpuset) I *think* that we only run into problems if
we use global constants provided by the library. But it might be
worth testing the example I sent before, even with dynamically
allocated handles. Linkers are deep, dark voodoo with unexpected
corner cases in round rooms. :-)
