Ouch.  That's ambiguous syntax.  Do you mean the programs 
shouldn't share the buffer, or that the library should ensure 
that sharing doesn't happen?  Either way fits the statement. 
I would have read it as meaning the first, but you seem to be 
saying that it's the second.

I'm not sure whether you were quoting the documentation, or 
reporting your understanding.  If you were quoting the 
documentation, I think it needs editing.

P.S.:  If I remember properly, in an earlier beta sharing the 
buffers in one's program resulted in run-time errors (buffer 
overwrites) that weren't detected...unless one wrote checks 
for the error.  This may have been a slightly different case,
