Peercoin - ppcoind parse error for pool start

Symptoms

Pool processor is outputting this on peercoin pool startup "(Thread 1) Could not start pool, error with init batch RPC call: {"code":-32700,"message":"Parse error"}"

Solution

Currently no solution as ppcoind appears not to support batch RPC commands, either node-stratum-pool needs to be updated to work around ppcoind or ppcoind gets updated to support batched RPC commands... the later is more appropriate and hopefully the solution.
