As I recall, applications generally shouldn't call *_size() functions at
all unless they need fine-grained control over buffer sizes.  The library
provides *_time_near() functions so that you don't have to worry about
these things.

I had some trivial problems with the ALSA code which I fixed by entirely
rewriting the plugin to use my own ALSA streaming library...and then never
quite getting around to telling anyone. :)

If there's interest I could make the code available (assuming I can get my
brain working well enough to remember something I did last June...)
