global-functions: $FetchHuge: another workaround for complete file

Browse source 
Turns out the workaround in $WaitForFile (commit
8231c3e833) is not sufficient. It helps
sometimes, but not always. Possibly depends on CPU speed and bandwidth
of internet connection... Who knows!? 🤪

But! Reading the file goes beyond the known file size. That's suspicious
and indicates this exact issue. So add a delay, and keep reading until
sizes are equal.
