[mpich-discuss] MPICH 3.1.1 building error when enabling per-object critical sections

[Balaji, Pavan]

Correct.  The per-object code was experimental and for research purposes (we only implemented it in ch3:sock and never fully ported it to ch3:nemesis).  Later IBM picked it up for their pamid device, where it is well supported.
