1271 * The original fix would call the default search hook before all the registered ones and pass

1273 * rely on. Which is the ordering between user hooks and the default runtime hook.
1275 * Registering the hook after mono_jit_init would let your hook run before the default one and
1276 * when using it to handle non standard app layouts this could save your app from a massive amount
1277 * of syscalls that the default hook does when probing all sorts of places. Slow targets with horrible IO
1278 * are all using this trick and if we broke this assumption they would be very disapointed at us.
1280 * So what's the fix? We register the default hook using regular means and special case it when iterating
1281 * over the registered hooks. This preserves ordering and enables managed resolve hooks to get the requesting
