Indeed, it's best to preallocate stacks; then you can guarantee
they'll be there when needed in a hurry!

If you are writing hardware interrupt handlers, consider my libhw
library, which does most of the hard work for you. It's currently in
beta, so any bugs should be reported - it works on my system, but
that's no guarantee for anyone elses!
