  The problem is related to termination sequence.  octave calls dlclose() for
all the modules it loads, from octave_dld_function::~octave_dld_function() at
shutdown time.  The modules in question have already had their dtors run, and
dlclose() causes them to be run a second time.

  We should probably make running the dtors idempotent, or unlink each dll
from the dll_list as we go.  I need to think about this for a little while,
more later.
