Personally I don't know what these dudes are smoking but for the last two years I've used Mainly BSD and Linux anda TINY bit of Solaris. And I can't find these problems.
The book is nearly 15 years old... it makes sense that the problems they discuss should largely be mitigated by now.

Hell I useLinux mainly which is "inspired" from Sun's OS which is Unix, and none of these things seem to happen to me.
Inspired by SunOS? How do you figure... from what I recall and can tell it is just a bad port of Minix.

This OS os something I use daily all day long for just about all tasks. Seriously one of the things they brought up was how the editor Emacs would dissappear taking a days worth of work and,.... Seriously who here as EVER experienced that?
Well... emacs has long been considered one of the most bloated and least stable of applications, but don't forget all of this was over ten years ago.

Take care to judge things in their context. :-P
