It should work. Note that the the malloced memory should be aligned in
order to get better sharing.
Within glibc malloc large blocks are mmaped, so they are automatically

I'm trying to work out if it's even worth considering this approach to
enable all memory used by in a system to be open to KSM page merging,
rather than only memory used by specific programs aware of it (e.g.
kvm/qemu).

Not sure if it is worth it, but you might want to look at ElectricFence
which does malloc wrapping in a somewhat similar way. It might save you
some code :)
I'll look into it, but I don't see this requiring

What I'm thinking about is somehow intercepting malloc() and wrapping it
so that all malloc()-ed memory gets madvise()-d as well.
You can also operate at a lower level and intercept mmap and brk, not
malloc. (But see below).

Within glibc malloc large blocks are mmaped, so they are automatically
aligned. Effective sharing of small blocks

Something like this would address the fact that
