The mallocng heap structures are actually more walkable. There is
intentionally no public interface for doing this, but I have some
debug code left over from development that you could link into
static-linked programs with a particular known musl/mallocng version
or patch into libc.so for debugging purposes. I'll dig it up and post
it. Ping me if I forget about it.
