The fun part is that it isn't the mlock in pkg. Commenting that call
out doesn't change anything, and I haven't had time to
single-step through everything...

The text, from an empty ~/octave:

The second run works just fine, although it too warns that
/home/ejr/octave/osdbi-0.0.3/x86_64-unknown-linux-gnu-api-v34+
doesn't exist. So the erroneous mlock must be called before it's
created.

The first pkg load osdbi also yells about mlock (in a fresh run
of Octave), while the second works.

So I don't think it's a pkg issue.

I'm also running into a segfault on quit with some combination of
atexit, global, and a type defined in a DLD... Haven't narrowed
it down enough yet to guarantee it's not my fault, but it *may*
be related if mlock is having issues.
