I started playing with this -- and this is pretty cool. 
Great work!

I had been avoid this because I figured it comes with a 
performance overhead (like -gprof does).  Or, perhaps it 
only has overhead when you use it (like Sun's strace). 
What overhead does compiling with --profile introduce?  Why 
not have it enabled by default?

Suggestion/Issue:  I have PDF issues with the 
TimingN.plot (gnuplot) files that it outputs.  They always 
issue the command 'set terminal pdf' and try to output a PDF 
file.  These create an error on my system and I have to 
manually delete them or change them to something like SVG 
or EPS.

Apparently, there's a license issue with libpdflite (which 
gnuplot uses to generate PDFs)... so some distro's won't 
have it installed.

Thanks,
Gabriel
