Ralph and I talked about this on the phone a bit this morning. There's several
complicating factors in using /dev/shm (aren't there always? :-) ).

I agree that /dev/shm introduces extra complications and should not be
the default. The FAQ text I provided was intended to suggest /dev/shm
as a session dir (or session root) ONLY for people who had diskless
nodes and thus no obvious alternatives to network-mounted /tmp.
If one wants to pursue placing the SM BTL's shared memory files in
/dev/shm by default, that is independent of adding something to the new
FAQ entry to address the diskless case.
