Re "normalize", this seems to be a bit of a kludge in dtrace that comes from
their inability to read the stats arrays at runtime. Systemtap users could
explicitly perform an equivalent scaling operation at print time, though more
clumsily for the histograms. Or the translator could provide an implicit
scaling facility (perhaps via an auxiliary scalar variable for each array),
which again is used only for printing. Unless I'm mistaken, the runtime need
not deal with this at all.
Re "printa", we've been over this several times, and the existing
sorted-foreach/print pair was not worse than the proposed sort/print sequence.
This leaves only iteration-limited sort/print, possibly combined with deletion,
which is already being discussed in bug #2051.
