I'm not personally working on the writable mmap() right now (ie
MAP_SHARED with PROT_WRITE) - it would be nice to have but it's not
trivial to implement and can be left for later without any major
problems. It's not impossible to write, and doesn't even need any truly
major rewrites of the mm code: it's just not too high on my priorities
right now (mapping readonly was much more important imho). That said,
somebody else may be working on it.
