NetworkReadStream actually saves whole response in the memory now. There is a pause mechanism in libcurl, but if libcurl is requesting something compressed, it would have to uncompress data as it goes even if we paused the request. Even though our own stream won't be notified about this data when when "pause" the request, libcurl's own buffer wound be expanding.
