We've tried hard to avoid copying data around, hence the use of
pointers instead of vector types for the i/o to blocks.  Also, behind
the scenes we doing some fairly fancy management of the underlying raw
memory.  We implement what is effectivly a circular buffer, but do it
in such a way that no user code needs to check for the wrapping
condition.  We do it by mapping a chunk of memory into the virtual
address space twice.

Regarding your last question, vector of what to string of what?
