7715a5898b [Mammoth] Naively free buddy allocated blocks. 
We don't yet attempt to merge them with nearby blocks.
Currently this reduces the number of 2 page blocks we allocate down from
40 to 29.

792e5155ba [Glacier] When resizing vector use the proper T constructor. 
Previously when we static_casted from uint8_t[] to T[] we ended
up not properly initializing the objects in the array. This caused
issues where garbage memory provided by new was treated as a legitimate
object.

Potentially in the future it would make sense to back vectors with
a simple byte array and do memcpys to move objects in and out as
needed.
