Robustness in the face of breakage is always good. Since you're
programming in transactions already, you have planned for failed
commits anyhow, so adding timeouts will probably not cause any
significant harm to your program.

The trick is dealing with statement timeouts on shared pool
connections over mod_perl and Apache::DBI. I haven't satisfied
myself yet that the timeout will be unset when the next connection
uses the DB...
