So the more objects you store in ruby the longer mark and sweep takes  
for GC because there are more objects to iterate over. Makes sense.

If you have a machine with 8 gigs of RAM and want to fill up all the  
memory to take advantage of it, can you will Ruby and Inline C?

So, the example Inline C looks like:

require ‘rubygems’  
require ‘inline’

class Example  
inline(:C) do |builder|  
builder.c “int method\_test1() {  
int x = 10;  
return x;  
}”  
end  
end

p Example.new.method\_test1

But would it be possible inside method\_test1 to do complex memory  
allocation and use all 8 gigs of RAM without all the ruby marking and  
sweeping?

Thanks.
