yes.

MemoryPointer.new and Buffer.new also zero initialize their contents,
unless you tell them not to.
e.g.
MemoryPointer.new :int  # allocates space for one int, zero initialized
MemoryPointer.new :int, 1  # allocates space for one int, zero initialized
MemoryPointer.new :int, 1, false  # allocates space for one int, _NOT_
zero initialized
