Well, disregard "disruptiveness" for now, which people can judge for
themselves by looking at the new code.

As for "costs" in terms of compile time/space and output size, you
should definitely present some preliminary data please.  For example,
the time/space for a plain bootstrap with vs. without the vta patches
applied.  Then another one with "-g" vs "-g0" vs whatever corresponds
to "full vta" - local variable debuginfo.

As for "benefits", you could give some gdb (or systemtap :-) session
transcripts that show the new data being used.
