Clearly you haven't looked at the valgrind massif data I posted earlier.
They clearly show that a lot of data is staying in memory. It'll require a
lot of digging to figure out exactly where the problems are. One I found out
is that synedit creates an image list with gutter symbols for every page!
That adds up to 3 M for the 450 file, which apparenltly aren't released when
closing the page. An other one is in zlib when reading lfm resources (there
aren't any in the 450 tes files afaik). Another few meg's hanging around.
