I've always considered
  for (;;)
preferable over
  while (1)
as the for (;;) expression does not require the compiler to expand
and evaluate a condition expression.

For the for (;;), the compiler sees the token stream <LPAREN>
<SEMICOLON> <SEMICOLON> <RPAREN>, and emits a closed loop, but
with while (1), the compiler sees <LPAREN> <CONSTANT> <RPAREN>,
and has to evaluate (either at compile time or at execution
time) the value of the <CONSTANT> to determine whether or or
not to emit the closed loop logic.

 
Or even:
 
:loop
    ....
goto loop

ITYM

  loop:
    /*Stuff happens here */
  goto loop;
