orbiter 783a4c9edb strong speed enhancements for the index cache dump and restore:
storage and loading is 30 times faster! a cache of 100000 RWIs needed 180 seconds
to store and 100 seconds to restore; now the same cache needs only 6 seconds to store and
3 seconds to restore. The cache size has decreased now by 30% (95 MB instead of 150 MB).
