1055 * - the initialization routine of a DLL can itself call LoadLibrary,
1056 * thereby introducing a whole new set of dependencies (even involving
1057 * the 'old' modules) at any time during the whole process
1058 *
1059 * (Note that this routine can be recursively entered not only directly
1060 * from itself, but also via LoadLibrary from one of the called initialization
1061 * routines.)
1062 *
1063 * Furthermore, we need to rearrange the main WINE_MODREF list to allow
1064 * the process *detach* notifications to be sent in the correct order.
1065 * This must not only take into account module dependencies, but also
1066 * 'hidden' dependencies created by modules calling LoadLibrary in their
1067 * attach notification routine.
1068 *
1069 * The strategy is rather simple: we move a WINE_MODREF to the head of the
1070 * list after the attach notification has returned. This implies that the
1071 * detach notifications are called in the reverse of the sequence the attach
1072 * notifications *returned*.
1073 *
1074 * The loader_section must be locked while calling this function.
