// Sumatra notes:

// - we removed non-windows code

// - we only use multi_threaded_global threading policy, support for other

//   policies has been removed

// - we replaced use of stl with our Vec

//

// TODO: optimize storage. Instead of having a Vec inside each has_slot,

// they could use linked list and only a single pointer to the list.

// allocations would be done from a single VecSegmented and freed item

// would be put on a free list, so that we can reuse them



#ifndef SIGSLOT_H__

// including <list> at this point breaks debug compilation

// under VS2008 due to the redefined operator new
