  I am kind of torn on this issue: while the additional buffer is
current eden size at this time, it may not be the only source of an
additional safety buffer, or it might just be something calculated
based on it in the future.

So I would prefer to keep the fact that the additional buffer is
exactly the current eden size at this time implementation internal.

Thanks,
  Thomas
