I've considered that option. But /lib/* doesn't have any
debug info on most installations. Neither do the other commonly
installed libraries.

Also, deployment would be problematic, since this requires all
user systems to have full debug symbols, too. And it wouldn't work
on non-DWARF systems at all.
