Typical class has its fields all set to zeroes so .init member of this class
usually contains plain zeroes, which can result in intensive spam from
compiler. Consider this code:
---
class A
{
    int[10] a;
}

void main()
{
    auto a=new A();
}
---
which in compiled form takes 96kb and after raising array size to 10000,
compiled execatable takes 135kb. So as number of class declarations grows,
object code gets polluted with zeroes.
