That's why I inadvertently learned to love printf debugging. I get to 
see the whole "chart" at one. Granted, it's in a bit of a "The 
Matrix"-style "only comprehensible if you know what you're looking at" 
kind of way. Actual GUI graphs would certainly be nice. But all the 
data's there at once,  so no need for constant fast-fowarding and 
rewindi...oh wait, that's right, debuggers can't rewind either. ;)

Honestly, I *have* used and loved debuggers, and I still appreciate 
them. I do think they're great tools. But...I rarely use them anymore: 
After several years of being forced into printf-debugging (or worse!!) 
for various reasons, every time I go back to a debugger I feel like I'm 
debugging with my hands tied behind my back. Or rather, finding a needle 
in a haystack using only a microscope that's stuck on max magnification 
and can only ever move to the right. And it's exactly because of the 
debugger's "temporal blinders" - the inability to ever see more than one 
*instant* at a time.
