[squeakdev] Karatsuba multiplication in a plugin using slang,
is it doable ?

Karatsuba algorithm is a simple divide and conquer algorithm to fast up
LargeInteger multiplications which is worth above a few thousand bits.
(see http://en.wikipedia.org/wiki/Karatsuba_algorithm).
I would like to implement it in the LargeIntegersPlugin,
But:
 the algorithm is recursive
 it will create shortlived LargeIntegers at each recursion
So that makes me wonder if it is really doable in a plugin in slang,
given that relocation might occur and mess the pointers...
The idea to handle the algorithm in pure C is just so boring...
(in which case, it would be simpler to handcraft a GMP plugin).
Any advice?
