the gnu.org mirror is always slow for some reason, but only
for gnulib. it may only be for me, because routing in other
countries/networks may differ.
when i'm freshly cloning lbmk modules, gnulib is always really
slow, like 300KB/s (bytes, not bits)
i have 1gbps internet and wish to not have 2005-era speeds,
thank you kindly!
