gvk_mem_new made a one-slot []pointer per allocation, and turned the requirement's size and alignment into strings to read them as ints; gvk_list_drop_last rebuilt the spare-record list to drop its last entry; gvk_mem_id did the string round trip on every free. One slot is kept (gvk_map_slot), int() truncates a long, the spare list pops. Every Text.to_int(string(x)) in render3d is int(x) now. Vk.heap_bytes() (vk_mac.ll: malloc_zone_statistics' size_in_use; 0 on Windows) and examples/rendering/steady.ludic, in the suite: a buffer released and made again 5000 times and 600 whole frames gain 0 bytes each - the allocator before this, 1,120,000 over the 5000.

bump: patch

type: fix

**render3d allocates nothing in its steady state.** A buffer released and made again - what a
|
|
streamed or growing buffer does every few frames - left about 224 bytes behind each time: the
|
|
Vulkan allocator made a one-slot list per allocation, turned two 64-bit sizes into strings to read
|
|
them as ints, and rebuilt its spare-record list whole to drop the last entry. It now keeps one
|
|
slot, converts with `int()`, and pops. `Vk.heap_bytes()` reads malloc's live bytes (macOS), and
|
|
`examples/rendering/steady.ludic` holds render3d to zero: 5000 buffer rounds and 600 whole frames,
|
|
0 bytes each (the unfixed allocator: 1,120,000 over the 5000).
