[erlang-questions] Book: "Robust Communications Software: Extreme Availability, Reliability and Scalability for Carrier-Grade Systems"

I haven't read it.
There's one customer review. Here's an extract:
"It points out that many aspects of a modern computer
system (pre-emptive multi-tasking, virtual memory, many
short-lived processes/threads to handle task execution and
dynamic garbage collection) are actually detrimental to the
design of a carrier-grade system. "
"[the developer team] shouldn't be put off by the C++ code
in the early chapters."
You can read parts of the book on-line via books.google.com,
and from a quick perusal, I'd say that it's a pretty good book
if you want an introduction into how to best write a carrier-class
system in C++. From what he writes, you can extrapolate that
Erlang is "dead wrong" for carrier-class systems(*). But then one
needs to remember that his frame of reference is /mainstream/
programming technology. If you have the time, it might be useful
to read the book, then read Joe's book, and meditate over the
differences in approach.
(*) This would be the superficial conclusion based on the fact that
he dismisses dynamic processes (because POSIX threads are un-
suitable for such programming), preemptive scheduling (because
it forces you to use semaphores everywhere), and dynamic
garbage collection (because it's very difficult to write a dynamic
garbage collector yourself that doesn't cause long pauses).
If your starting point is that there is no realistic alternative to
C++ for real industrial work, I'd say this kind of book is a must.
