Reading over this, I wonder if the jerkiness might be sessionstore.js saving a whole bunch of data (JSON encoding it, then saving to disk). A simple search on google can leave the tab with 200-800K of sessionstore data to save every time. Even without that, it will tend to interrupt you every few seconds.
