-----------------------------------------------------------------

Seeing others results the "problem" seems to be merges are very slow on trunk on Snow Leopard
(where I've been running the tests).
I've attached the whole stdout for both executions. Soon will run the tests on a debian box
and post the results too.
Here are the results:
trunk
Time taken indexing: 927
Time taken closing: 283
Time taken whole process: 1211

3.4
Time taken indexing: 303
Time taken closing: 37
Time taken whole process: 340
