Mine is ~700 kilobytes long with ~400 buffers and unlimited history lists. So far I had no problems with such a large desktop: I rarely restart Emacs; desktop reading is quite fast (a few seconds); desktop saving takes 0.2 sec. I could try using auto-save-hook and see what problems it causes. >> A separate question is whether to auto-save the desktop using >> auto-save-hook by default or not.

In any case, there should be an option to easily switch it off. -- Juri Linkov http://www.jurta.org/emacs/
