Memory will be freed... is it possible you are not getting any rendering
happening? e.g. if you do something like:
for (i = 0; i < 100000; i++) {
o = edje_object_add(evas);
edje_object_del(o);
}
your memory will keep growing ad the objects will be queued for deletion after
2 more renders. you would need the main loop to go idle *AND* for there to be
visible changes in the canvas needing rendering. evas_norender(evas); exists
for these cases where you do a loop where you add/del objects and never show
them or have them rendered (and just use the canvas as a workbench). this
forces a "no rendering" render cycle that will clean up queued objects.
it's exceedingly rare to do the above without having your canvas go through
some rendering at some point.
also edje will QUEUE signals and process them in idle time. if there is never
any idle time in the ecore mainloop then the signals will just queue up and
not be processed. setting a file will produce some signals already (like "load"
"").
