Thanks for all your help and advice.
I have reached the following conclusions. You may wish to comment if these are correct.
1. Fuzzy Select and Select by Colour use only one processor core.
2. If there are enough "crawling ants" on the screen the processor will go to maximum and be unable to process software IRQs.
3. Ctrl-T, as a keyboard IRQ, has a high priority and any software IRQ is then processed instantly.
4. Changing the precision to 32 bit floating point does not prevent the problem if enough "ants" are on the screen.
With the number of pixels increasing in newer cameras the lack of multi-core processing could become a problem. Let us hope this will be solved when we get Gimp 3.
At least, I now know how to get round the problem - Ctrl-T.
