What's going on is that the server accepts persistent connections but
does not have a request timeout set, so libfetch, due to an unexpected
interaction between multiple buffering layers, hangs waiting for more
data while the server hangs waiting for the next request; then libfetch
times out and doesn't notice that it already received exactly the amount
of data it expected.  Most servers have very short request timeouts, so
they close the connection while libfetch is waiting, which libfetch
interprets as an EOF (which is an expected condition as long as it
received all the data it wanted) as opposed to a timeout (which is an
error).  Anyway, it was fixed in head in r261230.
