Detailed Description

template<class T>
class AlignedAllocator< T >

stateless STL allocator that aligns elements to the L1 cache line size.

note: the alignment is hard-coded to avoid any allocator state. this avoids portability problems, which is important since allocators are rather poorly specified.
