I generally agree, it's what I use too, but there are lots of cases 
where the spawn thread/fork model is a better idea.  Software such as 
syslog-ng is currently limited to just a single CPU, apache would be 
pretty horrible without, etc.

Really boils down to if the task can benefit from parallelism and is CPU 
bound rather than IO.  I suspect though you were not making a sweeping 
statement for all applications though :)
