Memory leaks

[skyper]

I always did forget to report it. So, this is the start. I gonna try to collect more information.

Working for hours on a session I noticed JOSM to use more memory than it was given with -Xmx.

• After closing JOSM there is much more memory freed than JOSM was allowed to use.
• I got a "Out of memory" warning uploading these days.
  • Saving the session and restarting did allow me to upload using only half of the assigned memory. Sadly, I did not save the session.

So far I suspect two different regions to look at:

• imagery cache
• relation editor, seems to use quite a lot of memory, especially, opening 10 or more at once.
