Set DOM Storage buffer size so that not everything ends up in RAM
When a database is opened the log file is read and if the write
buffer is large then it stays in memory, and this happens
every time the browser starts. By reducing the write buffer
the log file will be written into the database the first time
and then very little RAM will be used for that data.
