On my i686 GuixSD machine, the following command consistently fails:

  mhw@jojen:~$ guix download file:///home/mhw/texlive-20160523b-texmf.tar.xz
  guix download: error: sendfile: Broken pipe

The file is 2071190200 bytes, which is about 73 MiB less than 2 GiB.
I have 2 GiB of RAM and 4 GiB of swap.

My guix client is v0.10.0-1899-g0f971a0.  My guix-daemon is 0.10.0.

I tried adding the same file using 'add-to-store' directly from the
REPL.  'guile' exited with status code 141, without printing an error
message:

(status:term-sig 141) = 13 (SIGPIPE), which makes sense: the daemon’s
child process at the other end received SIGKILL due to an OOM condition.

We don’t see that from the CLI because commands ignore SIGPIPE (see
‘initialize-guix’ in (guix ui)).
