softupdates turned to be very stable for me at least running on decent 
hardware, and well configured hardware. most important is to avoid 
stupid configuration of hard disc caches (e.g. write cache enabled) in 
such environments, as they greatly increase failure rate while almost 
getting not the slightiest performance gain (try running bonnie, e.g.).

i run NetBSD, FreeBSD and OpenBSD with softupdates. never had trouble, 
even with a machine stressed by repeated power failures (yes, 
malfunctioning UPS)...
