This is a reasonable argument.  Unfortunately the other direction is
reasonable too: remember Stan's comment about adding new strata?
That's got maintenance cost for the rest of GDB, because the strata
aren't really meant to work this way.  And it may get in the way of
future development, e.g. the work that Stan and Pedro are doing to
support multiple processes and multi-core systems.

FWIW, I find your reason for putting it above process_stratum
convincing but not your reason for putting it below thread_stratum.
I don't see why it has to be in the target vector at all.
