We still encountered a gc_sweep in our use of Ruby 1.8 on Linux (v8).

Yes, there are several (Ruby) threads working during this gc_sweep.

of course this effects 300 machines ;-)

You can find an example on why this probably a good idea  in 
test.rb located in the  sample directory of Ruby's source tree - grep
for "Titans" - (just image the morass of extra rules you would need to 
define to resolve this example if you start of with  a simple
``intuitive'' lookup rule).
To throw in a little history, Ruby once had more ``intuitive'' and 
seemingly simpler class variable scoping rules. However, because of
their inconstancies they were dropped, and new rules were adopted
modeled more closely around the constant scoping rules (static scope)
- not however in contrast to the former that singleton classes are 
not valid scopes  (see Guy's post) for class variables.

Here is another ``weird'' example for your wiki.

---
class A
  @@var = :A
end

class B
  @@var = :B
end

class B
  $a = A.new
  def $a.var
     @@var
  end
end

class A
  $b = B.new
  def $b.var
    @@var
  end
end

p $a.var # :B
p $b.var # :A
