This problem was detected on a Pentium III running Red Hat Linux
2.2.19-7.0.8 and bash 2.04.11(1)-release.
The following command *always* returns values 0..3 in numerical order, no
matter how many times it's called:
echo $(( $RANDOM % 4 ))
While the entrance into the series isn't always 0, once the loop has been
started, the numbers *always* follow in numerical sequence.
This also holds true for at least one other mod value: 2, which will
always return 0 and 1, in sequence.
