I routinely multiboot most of my machines - the one I'm typing on has
DOS, XP, Win7, 11.10 and 12.04. (And a copy of PC-BSD.)

I've never once had a problem with multiple distros sharing a single
swap partition, & I've been installing multiple Linuxes onto single
machines since about 1997.

If one has hibernated and you boot a different one, that might cause a
problem, but if so, the saved state is discarded and the next time it
boots up from scratch, I believe.

Point taken, but with lots of RAM, swap is fading in importance. I
actually run some installs without any swap at all and it works fine.
You can use zRam for a bit of breathing space if needed, but with
512MB-1GB of RAM, I find you don't really need any swap space at all
in typical usage.
