Yeah you are probably right. But wait a moment, thinking about it some more the overrun bug is actually a quite critical bug in mainline, cause it quickly leads to memory corruption if two users of the SA have different alignment restrictions. And hell, there currently is at least the IB pool (256 bytes) and the VM code (4096 bytes alignment) using it, so this could be responsible for some of the VM corruptions we are seeing!!! Going to write a patch immediately, Christian.
