Startup improvements (#639)

Browse Source 
* Benchmark for testing startup performance.

* Make pool pass spare space to pooled item

The pool will result in power of 2 allocations as it doesn't have a
local state when it is initially set up.

This commit passes this extra space to the constructor of the pooled
type, so that it can be feed into the freshly created allocator.
