Re: [boost] [Formal review] Singleton library

I don't vote because I have not (yet) looked at the library itself, but 
from the review replies so far I'd like to moot that it may be too early 
to include a singleton library which:

  - is not MT safe
  - is not tested with shared libraries
  - seems not to be tested with many compilers(...several newer 
compilers...)
