From the A Giant Salute From OSDir dept.:
I have now departed from Sun and joined my own company, Monty Program Ab.

...I had told management that I thus would be submitting my resignation immediately as I strongly believed that the 5.1 release was not ready and that those problems needed to be fixed before it went GA. This action, together with other peoples´ efforts, did have the wanted effect and I made an agreement with Sun´s upper management to not initiate my resignation but instead stay around for three more months to help Sun work out things in MySQL Development and also give Sun a chance to create an optimal role for me within Sun.

The three months did stretch out to seven months, and the changes I had hoped Sun would apply to in the MySQL Database group to fix our development and community problems did not happen fast enough.
