Agreed. We thought that stat() was safe to call in the malloc init

Jeff, I agree that one would expect stat() to be safe; my comment
about "crafty things" wasn't intended as a judgement call on this
approach. I think the code is pretty clever, but it's a hard problem
when you are operating with no clear rules about what is permitted in
the init hook. :-)
Thanks! Just wanted to make sure we weren't unintentionally going
afoul of some established techniques that we weren't previously aware
of (wouldn't be the first time :-( ).
Otherwise, I can easily convert my "#if 0" hack into a patch that
checks for an environment variable. Jeff previously suggested
setting OMPI_MCA_disable_memory_allocator; is that the variable we
want to use?
Note that this would be a fairly Open MPI-specific environment
variable. This would be fine with me, but I don't know you want a
more generic fakeroot solution in case anyone else ever runs into this
problem...?
