How to always autosave to default session instead of the current one?

[cirosantilli]

I would like the default session to always contain the last buffers I was in, even if I have already saved another session before exiting.

A similar effect is possible with default_to_last 1 + autosave 'yes' + autoload 'yes', but the problem is that this saves on the current session, not on the default one, and when I close vim I often have many buffers which are only used for the moment, and I don't want them to be part to my last manually saved session which I will use many times.

I have tried:

let g:session_autosave = 'no'
let g:session_autoload = 'yes'
autocmd VimLeave * SaveSession default

but for some reason it generates a lock on the default session, and load fails at the next startup.
