To add more confusion, this resolved the issue where a machine can
boot without UNDIIF_ID_DEBUG, will now work with UNDIIF_ID_DEBUG and
HTTP.

However, it appears to exacerbate the issues observed on a Dell
OptiPlex 760, resulting in a boot failure to load ldlinux.c32 and a
seeming time-decaying transfer rate (doing only TFTP).
