prelink.  Nice concept.  Cut down on overhead by doing most of the
dynamic loader's calculations ahead of time and stuffing the results
into the executables.  Speeds up everything by, oh, let's be generous, 1%.  
We like it.

Except when it decides to write binary zeroes over a whole pile of
important things, like /bin/sh, but not *quite* blatantly enough
that all the broken things can easily be found... so the easiest way
to recover is to reinstall all the packages on the system... which
doesn't work, but that's a whole separate rant.

This turns out to be a known bug triggered by running out of disk
space.  (Ever hear of error checking, bozo?)
