Something happend with my MacBook Air after the last update to 10.8.3. Not only mine, my wifes too.

When sending and opening a mail with a pdf attachment, the fans start spinning and Mail is soon up in 100% CPU usage.

Opening the PDF in Preview at the same time forces Previw to also use 100% on the other core.

This never happend before.

The PDF file in this case is a 66k twopage PDF made from Numbers,

MacBook Air, OS X Mountain Lion, 2,13 GHz Intel Core 2 Duo, 4 GB RAM

Just this one. It is a timetable made in Numbers, and when we make a midres PDF from it, it behaves like this.
