As I recall, when the ELF loader in Linux loads a binary, it does so by mmap'ing it into the process address space (effectively copy-on-write).  Due to the way that Linux's VM does mmap, the same pages should be loaded into every binary, and they should be copy-on-write as well.  So, yes, it should be optimized; and, no, you shouldn't be required to fork them from the same parent.
