running pimeta with an arg, we create arbitrary shm segments #156

Closed stevieb9 closed 5 years ago

stevieb9 commented 5 years ago

This is clearly a bug.

In pimeta and pimetaerase, we need to check if a segment has been already created if an arg is sent in. If not, we need to die().

Consider how to manage this for calling new() as well.

Realistically, we can't just delete shm segs... that could destroy prod information.

Simply croak and provide a warning that there's no shm segment key existing.
