That's what I initially proposed. However, as Scott Olson pointed
out, there's already a fix for this:

which uses still-non-portable /bin/echo.

(I wish I knew about it a week before now - it wasn't a pleasant week for me).

Still an interesting result. I can understand if it failed
for systems with smaller amounts of memory, -- nope, it fails
with Celeron on a 64Mb system, but works on the same system
if I replace the CPU to a real PIII... Fun.
