Back in like the gizilienth years ago when I DMed PnP for a motley crew of outcasts and nerds, we decided on an unwritten rule with regards to being resurrected. Here it is:
When a God brings you back from death, you are bound to that Being for 10 days times your level.
This can be applied to BG. For example:
When Viconia dies at 4th level, and Garl Glittergold brings her back (why He would do this I have no clue), she has to sweep the floors of the church for no less than 40 days. Which means, you should not allow her to rejoin your party for said amount of time.
A small price to pay, but a fearful prospect to the hardcore gamer.
