Memory usage improvements for 4.11
The other day I went to buy a DDR stick but the shop was closed so the only solution was to sit down and fix some memory hungry applications ;).
These will be in 4.11:
- Fixed a bug where maildir resource would use 1 or 2GB when importing large folders. 
- Fixed a bug where mixedmaildir resource would also use 1 or 2GB. (Thanks to Martin Steigerwald for providing a a 77k e-mail folder). 
- akonadiserver wasn't clearing uneeded query caches. Saved 65MB here. 
- Kontact had 5 copies of all calendaring data in memory if you used summary view which accounted for 200MB with my big test .ical file. 
- KOrganizer grew infinitely over night under some circumstances. 
- KAlarm wasn't freeing editor dialogs, resulting in infinite memory usage over time. 
- Mysql got up to 25 MB of savings (4.12) 
Also, Dan Vratil and Vishesh Handa have been working hard on performance/memory of nepomuk and akonadi.
