Walk 9's fence named 256 frames of +16 B at gvk_tex_storage:244 and
m4_new:92, always under HudDay's and HudGuide's models. Neither site
makes 16 B: the blocks were intern's copies (lp_copystr), which never set
lp_site and so were charged to whatever allocated last. The HUD's clock
and the guide's distance are a new text every few seconds, and each first
one was a malloc kept for good.
lp_copystr now copies into @lp_istore, 4 MB in the binary (untouched pages
cost nothing), and falls back to the heap only past it; lp_free ignores a
pointer into the store, so a text freed after it was interned is no fault.
value_num_text - the text a screen shows for a number, dropped whenever
the number changed - is interned the same way and its string() given back.
Checked: a program interning 100000 texts gets every one back right, the
same text as the same pointer, a freed one harmless; the headless valley
compiles, with frame_allocs, frame_keeps and birth_leaks at 0.
