For Slush members wondering what is going on with threshold delayed payments...

"Typically, the pool sends confirmed rewards which are over threshold to users every hour.

For security reasons, the server's hot wallet (keeping funds immediately available for payouts) has quite a low balance. When the hot wallet becomes empty, the pool administrator has to load the wallet from the cold storage (a highly secured offline computer keeping pool's bitcoins). Since this process cannot be automated and only very limited number of people has an access to cold wallet, it can introduce a few hours' delay in sending coins to user's wall
