Is it a good idea to use one and the same swap-partition for two diferent Linux distributions installed in a dual-boot-system? I figure they don't run at the same time, but I don't know if anything is left on the swapdisk after Linux shuts down that could be mangled when using the same swapdisk with another Linux then...

Once you shutdown or reboot, anything in swap is wiped out. And swap should rarely be used doing routine computer stuff. If you notice you ever start using a lot of swap, either you need more ram or something is wrong with your ram.
The only time it's an issue is if you use software-suspend/hibernate. Ram is saved to swap in that circumstance, and you could potentially lose quite a bit of data if you brought up another distro after suspending.
It could be a little more complicated to share /home than sharing swap. You may want to have different custom configurations that use the same filename. I hope I do not violate the forum rules when I post this link (since it is in german): http://www.linux-user.de/ausgabe/200...tri/index.html
They have some interesting hints how to accomplish a common /home.
