As a side-effect, ordinary non-mining nodes will download and upload blocks
faster if those blocks were produced by miners using similar transaction
filtering policies. This means that a miner who produces a block with many
transactions discouraged by your node will be relayed slower than one with
only transactions already in your memory pool. The overall effect of such
relay differences on the network may result in blocks which include widely-
discouraged transactions losing a stale block race, and therefore miners may
wish to configure their node to take common relay policies into consideration.

New bytespersigop implementation
--------------------------------
The former implementation of the bytespersigop filter accidentally broke bare
multisig (which is meant to be controlled by the `permitbaremultisig` option),
since the consensus protocol always counts these older transaction forms as 20
sigops for backwards compatibility. Simply fixing this bug by counting more
accurately would have reintroduced a vulnerability. It has therefore been
replaced with a new implementation that rather than filter such transactions,
instead treats them (for fee purposes only) as if they were in fact the size
of a transaction actually using all 20 sigops.
