This has been mentioned before. I was unable to find any information other
than the code itself which wasn't all that transparent to me.  And the stack
allocate was soooooo simple.  Is aligned_storage part of boost?  Is it
documented anywhere?  Is it part of any test suite?  Has it been tested for
portability?  In general I would prefer a boostified component over a
homebrew one.  I'm really not sure of what the status of aligned_storage is.
Also, the nameitself didn't make it clear to me that its intended purpose
was identical to that implemented by stack_allocate.
