In this case it would be better not to call $TYPO3_DB->connectDB()
directly, but use the underlying public function $TYPO3_DB->sql_pconnect().

Die'ing in a library function sucks!

Alternatively I'm open to change $TYPO3_DB->connectDB() so that it takes
a parameter telling it not to die on error. Instead of dying it could
either report FALSE, return an error message or throw an exception.

Anyway for tslb_eidttools I think a die with an error message is not the
right choice as it might be used in an AJAX or other non HTML contexts.
