the limit was too high. This prevented us from raising the limit
earlier. The qemu issue seems to be fixed (according to my testing) and
we may remove the 32Mb/s limit.
IIRC, the problem wasn't with QEMU, but rather that libvirt was passing
QEMU a file descriptor pointing to a plain file, on which O_NONBLOCK
does not work (thanks POSIX). We fixed libvirt to pass a pipe instead
to address that.
