getwork/RPC-related freeze at shutdown #2300

When pointing the shiny new Avalon ASIC miner directly at bitcoind (getwork mining), blasting bitcoind with a large number of requests,
- cgminer reports several 'get failures' (to be investigated; a separate issue from this)
- bitcoind stalls in the middle of shutdown
- this shutdown-freeze symptom does not occur outside of ASIC miner getwork testing.

Possibly related: #2204

Isn't the first one expected? IIRC we decided on IRC a number of months ago that getwork mining was basically unsupported because the optimizations to make it perform fast enough were too invasive - or something along those lines.

Does 2/3 occur even if you stop the ASIC mining before/during shutdown?

No longer relevant, getwork has been removed.
