really any advantages... I particularly think it's a really bad
idea to have a complex and potentially race-condition-prone bit
of infrastructure implemented three different ways rather than
having one implementation used everywhere -- it's just asking
for obscure bugs on the non-x86 hosts.
Really it just breaks the general rule I prefer to follow that
you should write your code in the 'mainstream' of an API/platform;
if you head too close to the shallows you're liable to hit a rock.
