1113 * - we have to respect the module dependencies, i.e. modules implicitly
1114 * referenced by another module have to be initialized before the module
1115 * itself can be initialized

1117 * - the initialization routine of a DLL can itself call LoadLibrary,

1120 *
1121 * (Note that this routine can be recursively entered not only directly
1122 * from itself, but also via LoadLibrary from one of the called initialization
1123 * routines.)
1124 *
1125 * Furthermore, we need to rearrange the main WINE_MODREF list to allow
1126 * the process *detach* notifications to be sent in the correct order.
1127 * This must not only take into account module dependencies, but also
1128 * 'hidden' dependencies created by modules calling LoadLibrary in their
