from many folk. o The reseed process is now a kthread. With SMPng, kthreads are pre-emptive, so the annoying jerkiness of the mouse is gone. o The data structures are protected by mutexes now, not splfoo()/splx(). o The cryptographic routines are broken out into their own subroutines. this facilitates review, and possible replacement if that is ever found necessary. Thanks to: kris, green, peter, jasone, grog, jhb Forgotten to thank: You know who you are; no offense intended.
