'/tmp/hyperspace.sock'

[da2x]

/tmp/hyperspace.sock is too broad and permissive. It limits you to one hyperspace per system instead of one per user. It should only be readable by the user who created it. Currently, it’s world-readable.

It should probably live in ~/.hyperspace/socket (where it could also act like a singleton lock) or at least /tmp/$uid/hyperspace.socket.
