-// SharedHandles is a simple class to stash and find windows object handles
-// given a raw block of memory which is shared between two processes.
-// It addresses the need to communicate a handle value between two windows
-// processes given that they are already sharing some memory.
-//
-// This class is not exposed directly to users of the sanbox API, instead
-// we expose the wrapper methods TargetProcess::TransferHandle( ) and
-// TargetServices::GetTransferHandle()
-//
-// Use it for a small number of items, since internaly uses linear seach
-//
-// The use is very simple. Given a shared memory between proces A and B:
-// process A:
-//  HANDLE handle = SomeFunction(..);
-//  SharedHandles shared_handes;
-//  shared_handles.Init(memory)
-//  shared_handles.SetHandle(3, handle);
-//
-// process B:
-//  SharedHandles shared_handes;
-//  shared_handles.Init(memory)
-//  HANDLE handle = shared_handles.GetHandle(3);
-//
-// Note that '3' in this example is a unique id, that must be agreed before
-// transfer
-//
-// Note2: While this class can be used in a single process, there are
-// better alternatives such as STL
-//
-// Note3: Under windows a kernel object handle in one process does not
-// make sense for another process unless there is a DuplicateHandle( )
-// call involved which this class DOES NOT do that for you.
-//
-// Note4: Under windows, shared memory when created is initialized to
-// zeros always. If you are not using shared memory it is your responsability
-// to zero it for the setter process and to copy it to the getter process.
