I decided that I wanted to see if there really was a measurable
speedup, so I ran some trivial non-scientific tests. I compiled the
Hurd four times (each time just after a fresh boot) and these are the
results. If they can be trusted, the new implementation shaves off a
few seconds.
Old implementation
real 38m11.190s
user 0m0.010s
sys 0m0.000s
real 37m52.320s

New implementation
real 37m45.180s
user 0m0.010s

real 37m35.680s
