You can store arbitrary things in the buffer using the bufferDynamicValueA accessor. There are examples of usage in Vim keymap and Dired. You can store strings at the editor level using dynA, in a similar way.
I find a 10 second delay very huge though; you might benefit from using Data.Binary. Hope this helps, JP.
