Stone may hang on AIX when swap space becomes very low

When swap space on AIX becomes very low, AIX sends SIGDANGER. The Stone
did not respond properly to this, and would hang.

Workaround

In general, avoid low swap space conditions, but be particularly careful
on AIX.  If swap becomes low and the stone continues to hang after memory
is recovered, you will need to restart the stone.
