OK, thank you for the clarification.
With that in mind I'll continue to follow a staggered approach:
* A release with libmalloc-extras.so.0 for LD_PRELOAD (2.28)
* Gain experience with libmalloc-extras.so.0 usage (Future)
* Potentially provide a libmalloc-extras.so for direct linking (Future)
The notion of providing an "official" interposer still appeals to me
from the perspective that it can deliver features we would not normally
turn on in regular libc.so.6's malloc API.
Cheers,
Carlos.
