# Procedure to check if sequence of values in listval follows linear trend
# adding the same delta on each step.
#
# The function does statistical estimation of the mean variation of the
# values of the sequence, and dispersion, and returns true only if both 
# dispersion and deviation of the mean from expected delta are within 
# specified tolerance.
#
# If mean variation differs from expected delta on more than two dispersions,
# the check fails and procedure raises error with specified message.
#
# Otherwise the procedure returns false meaning that more iterations are needed.
# Note that false is returned in any case if length of listval is less than 3.

# See example of use to check memory leaks in bugs/caf/bug23489
