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
user    0m0.000s
sys     0m0.000s

New implementation

real    37m45.180s
user    0m0.010s
sys     0m0.000s

real    37m35.680s
user    0m0.000s
sys     0m0.000s
