Apache::DBI's docs say:
Apache::DBI [...] has a limitation: it keeps database connections persistent on a per process basis. [...In] a heavy loaded Web-site where every user connects to the database with a unique userid[, e]very server would create many database handles each of which spawning a new backend process. In a short time this would kill the web server.
DBIx::Connector's docs do not mention this limitation, but does it still apply to DBIx::Connector, too, in a mod_perl2 context?
