Well, worst case is 16k - 2...

Relate this to the current 4k-pages waste: the expected wastage per binary
is 2k+2k; 8k-page binaries will have an expected waste of 4k+4k.

With the current population of /bin, /sbin, /usr/libexec, /usr/bin and
/usr/sbin (~500 files) the extra disk space needed will amount to something
like 2MB.

Actually, a quick survey of data segment sizes on my sparc (8k page size)
shows that most binaries have a data size of 8k, which leads me to the
suspicion that the data segment sizes are not actually very evenly distributed.
