An option on  ld  can be used to make the text of an object file shareable
among processes.  From the ld manpage on Ultrix:

     -n             Arrange (by giving the output file a 0410
                    "magic number") that when the output file is
                    executed, the text portion is read-only and
                    shared among all users executing the file, an
                    NMAGIC file.  This involves moving the data
                    areas up to the first possible pagesize byte
                    boundary following the end of the text.

For programs not using shared libraries, this may help alleviate thrashing.
