There's still some embedded work where cycle twiddling matters - I
last did some in 2001 (?).  I had to hit external hardware every 64
cycles - on the cycle - while multitasking other processing.  That's
probably the most fiddly code I have ever done.  I ended up writing a
little ruby script that worked as roughly half an assembler and
counted cycles for me and colorized my source code if my counts where
off - it made everything way easier.  Ah, memories... :)
