malloc() infra takes more than this IIRC (something like up to 32 bytes on
64-bit platforms) or comparable sizes. Yes, the malloc() along with the
linedisp structure might make sense, but will require more invasive change.

Do you want me to drop this one from the set?
(I have no hard feelings about it, as I see better way and just having no
 time for taking care about, as it's not the main point of the series.)
