I'd guess because setting up a srcprops is critical to start-up
performance, and a double cell doesn't have enough slots to store all
the common properties (filename, pos, copy) directly (as your change
makes clear).
So I'd expect --debug start up to go a little more slowly after your
change. Did you make any measurements?
Also, did you find that the change saved a lot of memory for Lilypond?
It's not obvious to me why it should have done, just moving srcprops
from a specialized storage to the general cell heap.

Neil
