Build time up to the failure was 58 minutes on my machine (which is dualcore
but currently runs in UP mode).

Given that MIPS today spans the range from said Linksys router over workstation
class machines like the buildds up to a SiCortex SC5832
<http://www.sicortex.com/prod_sc5832.shtml> I can't follow your rationale.
