The ISs on the input list can belong to subcommunicators of comm, and the subcommunicators Many bron the input IS list are assumed to be in a "deadlock-free" order. Many br
Local lists of PetscObjects (or their subcommes) on a comm are "deadlock-free" if subcomm1 Many brpreceeds subcomm2 on any local list, then it preceeds subcomm2 on all ranks. Many brEquivalently, the local numbers of the subcomms on each local list are drawn from some global Many brnumbering. This is ensured, for example, by ISPairToList(). Many br
