Page (4KiB) alignment for memory pool

[cohdan]

Hi,
I'm trying to create a memory_pool with 4KiB alignment. I tried to wrap the memory_pool with aligned_allocator, but it fails as the max alignment from a reason I can't understand is 8 bytes. Is there a way to create an allocator that allocated 4K buffers with pointers aligned to 4K?

I need this in order to handle some direct IO to 4K block devices.
Thanks!
