Hi Rich,

I can get rid of the <= case. glibc's paranoia might not actually make
sense. Actually, presumably one can just get rid of the entire loop,
assuming the < 256 guarantee continues to hold.

I'll send you two patches, one that moderately fixes up this v1
(called v2) and one that gets rid of the loop entirely (v3).

Jason
