Comment(by Quozl):

 Reproduced on XO-1.75 build 20.

 When /var/cache/yum is empty, the problem is way more likely.  When is it
 filled, the problem is unlikely for small packages.

 When the yum command is prefixed with ''olpc-nosleep'' the problem does
 not occur.

 Using "strace -ff -o yum yum install -y PACKAGE" the logs suggest a
 problem with pipes and resume.  An instance of urlgrabber-ext-down is
 terminating with exit status 1, shortly after an EPIPE on the write to the
 pipe connected to the parent process.  The child receives a SIGPIPE.  The
 process exit cascades to a SIGCHLD on the main yum process, which appears
 to be handled as an exit on user request.

 Continues to not reproduce on XO-4; no surprise now, given resume is
 implicated.

 Needs more diagnosis as to why EPIPE occurs.
