Well, a 5 Mbyte [1] overhead isn't really that much, IMHO.  You'd need to
run a lot of (different; if they're the same, the text will be shared)
applications to get any measurable benefit.  Eventually, it would be
nice to have dynamic linkage, but I can see why it isn't a priority.


[1] On my Linux system, the overhead seems to be less than 2
Mbyte. 5 Mb is the figure used by the OP.
If I haven't seen further, it is by standing in the footprints of giants
