True, but sometimes you find old bugs or poor code by implementing new things,
but the main priority is of course to make it rock-solid, and that's why
I think it's not very good that XaAES uses kmalloc/kfree for nearly every
little chunk of memory. I only may help to debug the hard way ;)

There's still a design-bug concerning slb if used inappropriately (kernel frees the proc-attachment,
and XaAES also -> invalid MAGIC) but that's complicated.

Another bug may lie in XaAES executing USERDEFS in user-mode, which is also complicated.
