Why are you running swap on a raid device?
You DEFINITELY want to do this, otherwise, when 1 disk dies, so does your
system if its using that swap!
Most systems don't use swap. Servers probably never should.
Most recommendations I've read are NOT to use raid for swap.
Some processes might die, but usually the system survives when swap is
demounted.

2.3 Swapping on RAID
There's no reason to use RAID for swap performance reasons. The kernel itself
can stripe swapping on several devices, if you just give them the same
priority in the /etc/fstab file.
