Elliott Hughes 1946d3bca8 init shouldn't call DumpState by default. 
The cost of generating and throwing away a bunch of stuff that no one
normally sees is high enough to be worth avoiding.

Here's AOSP ToT on N9...

It's less than a second, but one problem is that the cost of the current
dumping is proportional to the number of init.rc files, so the more
cleanly you factor things, the more it would cost.
