Debayer process status reporting inconsistent

[johnpane]

I am unsure if this is simply a cosmetic problem or a sign of an underlying substantive issue. Running Debayer on 10 cores, the status reports on the console show "VNG demosaicing: done" half of the time, but the word "done" is missing the other half of the time. These approximately alternate, but not perfectly. Below is a console excerpt covering the processing of 20 images.
