Very cool.
Sorry for being rusty here, but is it safe to call fuword in the middle
of issignal()?
The reason I ask is because it looks like proc lock is required for this
block, and I forget it fuword(9) can fault.
If fuword(9) can fault then I don't think you can do this.
You'll need to use something like fuswintr(9) or wire the page down
using vslock(9) or something.
I am probably missing something?
