pub fn set_keeping(on: bool)Expand description
Said once by a process that exchanges every few minutes for a long time
(a phone’s background service): the memory and the logs of lines are kept
between its exchanges (Kept, LINES), rather than read again at each.
They weigh some tens of megabytes with many texts shared (about 30 MB for
10 MB of texts): a window’s process, which holds little between its
minutes, reads them again at each (docs/android.md, “In the background”).
