I thought that since as_area_create() doesn't allow this, changing flags after creation would make no difference. It would seem that this restriction is some kind of leftover from the past.
I am quite puzzled here: There must have been some reasonable motivation behind this (besides security), but the comment near the condition in as_area_create() which explicitly disallows the creation of writeable and executable areas offers no explanation.
Those lines were committed by Jakub J. as revision 1048 back in the old Subversion repository. Jakub, can you please remember what was the motivation for this?
