Ah, wanting to learn another hard lesson. :)

>>>The ostensible reason is I am allocating image buffers that are passed on
>>>to an unknown number of asynchronous clients. I store them in a ring that
>>>[hopefully] has enough slots so even a slow client will have time to send
>>>the newest buffer before it is trashed in favor of a yet newer image (4 or
>>>5 down the line). That code is very simple and works fine. The alternative
>>>seemed to be copying each buffer for each client to which it's due, which
>>>I wanted to avoid.
> 
>>Wow, some more scary statements.  '[hopefully] has enough slots' 
>>Really, you should insure that you have enough.  One of two solutions, 
>>depending on the problem.

>  ...
>  I do this:
> 
>>2. finite number of slots needed - static slot allocation.
> 
> The number of slots is fixed by a compilation constant.  There are tests
> to harmlessly catch an overrun on the ring.
> 
> Each slot points to a dynamically allocated byte buffer for whatever size
> image has been returned on that round. These are what I tried not to
> recopy. I ended up with a mix of local and remote buffer allocations,
> which is just a _REAL_Bad_Idea(TM)_; it's going to go, NOW.
