I had to look this one up. According to the spec, a shared struct does 
not mean that the variables of that struct are automatically shared. It 
means that the members of the struct are shared:

   http://dlang.org/struct.html#ConstStruct

Here is a test:

import std.stdio;

shared struct S
{
     int i;
     int[] a;
}

void main()
{
     auto s = S();
     writeln(typeid(s));
     writeln(typeid(s.i));
     writeln(typeid(s.a));
}

According to the output, the members are shared, not the struct:

deneme.S
shared(int)
shared(shared(int)[])
