Making "read from file" less blocky.

[Tom Glod]

 Dar, Yes...I understand.....it is a blocking operation no matter what I
can just introduce breaks in the blockiness.  So I'm not expecting a socket

Those are very good suggestions to try.... thank you.

Jerry, I will give that a try, it looks promising.....even a little
improvement would be better and sufficient for this need, and I can use it
sparingly.  Thanks alot!  Onward indeed.
