That is one way to do it. What I was planning is: 

1. block_size is usually something like 512 or 1024
2. choose a sound card fragment size that is say 2 or 4x larger than
block_size
3. use ordinary blocking i/o with /dev/dsp since you don't want to run
way far ahead anyway; don't use a separate thread
4. for each tick, do blocks until there is less than block_size samples
left in the tick. at that point just generate a block that is the size
of the remainder. 
5. start a new tick
