I agree with tedster, I am sure it is computer heavy. But let us stick to Page Layout Algorithm: I think one can easily understand that painting the layout of each page (!) needs more CPU than just reading and parsing it as plain text. Google has already suggested that it is a manual update.
But, all this DOES NOT MATTER. The REAL QUESTION that has to be asked is when they will/did rerun it. Because if it has been rerun and people did not see changes, then they were 1.probably hit by something else from the beginning (i.e Panda in mid-January) or 2.their changes were not sufficient (still ad-heavy) or 3. their pages have not been recrawled yet.
Since I have not seen anybody recover from it yet I still have hope that I was hit by the Page Layout algorithm and not by Panda (which would be 10 times worse).
