There is a lot of dead code in gnumach that I removed in oskit-mach.  And I
bet the drivers are the majority of the LOC in any kernel (that has drivers
in it at all, which is why oskit-mach itself is so small).

Things like libc, and especially the oskit, have a lot of code that never
actually goes into any part of a GNU/Hurd system.  So these kinds of counts
are always pretty unrealistic.  (However, that is only appropriate as you
then multiply them by the utterly ludicrous development effort estimate
based solely on source language.)
