I would be very happy to see a libposux, even more so, if the content
were standardized across Linux and FreeBSD.

Remember that shared libraries, you load all or nothing.

With old fashioned .a libs, you cherrypicked the bits you needed.

It can be argued that we should just dump everything in libc, but
first, that would impair portability from FreeBSD, and second, it
would be just plain sloppy...
