- (Preface: the last version I have of Holmgren's stuff is v4.)
-
- The original _works_ but does so poorly. It spills the buffers
- almost every time, so where you have large buffer sizes, and
- small Seeks, you end up re-reading large amounts of data many
- times. (A specific example: seeking forward or backward, message
- by message, in a mail folder.) I consider this badly buggy
- behavior.
-
- Holmgren's stuff claims to have fixed a bug or two (specifically
- in SeekAsync() including this buffer-spill issue), but I find it
- plain broken. I've taken some of his other patches and moved them
- into my source.
