It's a Cism near as I can tell. As you know it's the functional equivalent of 
while(1) {}. As for the principle behind it... the entire (;;) evaluates to 
an unmet condition. thus the for loop never ends. Personally I prefer (for 
readability purpose) the while(1). But most compilers today will optimize 
both such that the condition is never met.
