The shmem_team_destroy routine is a collective operation that destroys the
team referenced by the team handle argument team. Upon return, the
referenced team is invalid.
This routine destroys all shareable contexts created from the referenced
team. The user is responsible for destroying all contexts created from this
team with the SHMEM_CTX_PRIVATE option enabled prior to calling this routine;
otherwise, the behavior is undefined.
If team compares equal to SHMEM_TEAM_WORLD or any other predefined team, the
behavior is undefined.
If team compares equal to SHMEM_TEAM_INVALID, then no operation is performed.
If team is otherwise invalid, the behavior is undefined.
