The fetch no longer seems to suffer from the large 
regression, it is now faster (~7m) than 1.7.7 (which was 
+15m).


As a quick note, if I comment out the 
invalidate_cached_refs() call in write_ref_sha1() on line  
2065 (on top of 9944c7), it is still much faster, only ~2m.  
Perhaps growing the array on the fly with many refs is still 
be too inefficient?
