There are two options:
1) Pay all frozen balances proportionally from available funds (1770 returned coins + my reserves), then close pool and forget or remember this;
2) Try to cover a part of frozen balances using fees, withdrawal limits and (possible) luck. This could take some time, but the final value will be higher than 1/3.
Both options are not good for those who make withdrawals rarely, I think. Probably It would be better to pay available funds depending for last withdrawal day. That is, at first pay for work that have been performed prior to 22.06.2013 if no withdrawal have been maked since this day, than for work performed in 23.06.2013, etc. until there are available funds.
Than start normal pool work
