I guess that the server or network was temporarily down, each part
waited for timeout, when it expired no data were written. We must
interrupt saving and report error in that case.

QGIS hangs if server hangs. The raster architecture is ready to run
saving in a separate thread. The pipe is cloned  including the
provider. What is missing is some 'download' (saveas) manager. Martin,
do you see any problem in running save as in separate threads?

It is the problem I mentioned in previous mail, I am working on it and
I'll keep you informed.
