In the v1.5 README, I see this:
Enables thread lock support in the OPAL and ORTE layers. Does
not enable MPI_THREAD_MULTIPLE - see above option for that feature.
This is currently disabled by default.
I don't otherwise find opal-multi-threads at all in this branch. It
seems to me, for such an option, one needs to move to the trunk.
Is this an error (anachronism) in the v1.5 README?
