In general? Sure, why not? I assume you wish to continue interposing malloc
family functions.
As the API for determining TLS and stack boundaries? I'd prefer we had either a
function/callback API or probe-based API. Even a public AS-safe allocator API,
when interposed, is just a hack for getting at what you really want which is
the TLS and stack boundary information.
