      xmrblocks needs monerod's RPC login: --rpc-login guards both of monerod's
      RPC servers, so without it the mempool view and the pusher get 401.

# Generous on purpose. xmrblocks opens the whole LMDB before it binds, and this
# pool is a spinning-disk mirror - it logs "The blockchain is on a rotating
# drive: this will be very slow" and took 98 SECONDS to come up on first start.
# 90s was not enough and produced a scary failure on a service that was fine.
