I'm confused by this.  I could have sworn that the standard cc -p
profiling uses monitor() to build an instruction-count profile as
well as a function entry count (with the instruction PC "bin size"
set to some default, which presumably could be adjusted simply
enough by keeping in in an extern, e.g. __pc_bin_size, for use by
the mcrt0.o startup code.

I know that even on 6th Edition UNIX I was able to (via "prof -v")
produce nice graphic histograms showing instruction usage density
and cumulative use along the PC address axis.  Don't tell me this
feature got lost as a result of the Berkeley "improvements"!
