Unless you have a very unique optimizer, it is usually better to use the
for(;;) form rather than the while(1) form.  Reason is:  while(1) is
ALWAYS evaluated (ie. : is 1 TRUE? if so, continue) before each iteration,
whereas for(;;) compiles as a simple branch or jump instruction with no
test and no conditional branch.

simply loops with no checks.
