I understand now the nature of the problem, and the difficulty of fixing it.
But I think that it's more than an aesthetic problem. On a slow link
like PPP you need to know more often than every megabyte (IE more often
than every 15 minutes) that the transfer is successfully going. I
thought the whole purpose of HASH was to give that kind of real-time
feedback.
Since the code is assembling everything in memory, one cannot even look
at the size of the output file to determine if anything is happening.
It is too easy to think that FTP is hung.
Might it be possible to do some kind of buffer flush every minute of
real time or some such?
