# to mask out the error - never abort neither log in result file - in setting 
# to read-only variable.
# It is assumed that the new value is equal to one the var was set to.
# Such situation happens particularily with binlog_format that becomes read-only
# with ndb default storage.
#
# when generate results always watch the file to find what is expected,
# the SET query may fail

# script accepts $maybe_ro_var the var name and $val4var the value
