does not repsonse well to sigint(ctrl-c)

[garyng2000]

if I start geth in a command window(linux), ctrl-c is received but the shutdown process never complete. the same is true if I put it into systemd.

end up need to use the brute force harsher kill signal. this is not a big issue

well it was in the past for mainline geth as the database was not flushed so killing too harsh can result in lost transaction which has already been mined. of course this is not an issue for testnet/mainnet but private network(single node) can be problematic. geth I think have somehow fix this losing transaction.

just a FYI for now
