My understanding is that you need to add the "flushable_tag" category 
tag to your filter. In addition, the filter must add support for the 
flush function. Look at "flushable' and "flush" in the docs.

In addition, if you search the iostreams source tree for "flushable_tag" 
you should find some example code.

I don't know what is the "best" way to do it.
