It is not:
Single pack = 17.1s
66 packs with commit f7c22cc6 = 18.4s
66 packs without commit f7c22cc6 = 24.9s
The point is that having many packs doesn't impose a significant
overhead anymore when comparing to the single pack case.

Having only to set gc.auto=0 to disable it entirely is also a good
thing.
