This fixes problems allocating bouncebuffers on alphas where there is only 1 chunk of memory (unlike PCs where there is generally at least one small chunk and a large chunk). Having 1 chunk had been fatal, because these structures take over 13MB on a machine with 1GB of ram. This doesn't leave much room for other structures and bounce buffers if they're at the front.
