My impression is that __DO_NOT_DO_WEAK__ was added for the purpose of
putting all the pieces in place and then `lifting the curtain' all at
once; though it would be nice if that had actually happened (within a
reasonable timescale), it's clearly not necessary.

As a sidenote, I've been experimenting with a table-driven syscall
stub generation method to handle internal names and weak aliases
(where necessary) flexibly, which is the main piece missing; I intend
to commit this soon.
