glibc can raise its dynamic mmap threshold above these MB-scale allocations, routing later scrollback segments through brk. Closing windows then leaves the freed segments stranded in allocator bins and grows the long-lived kitty process. Back the existing batched segment layout with anonymous mappings instead. This preserves zero-initialization and pointer layout while ensuring the memory is returned to the OS when a history buffer is cleared or destroyed. Co-Authored-By: Claude <noreply@anthropic.com>
