Right. But in practise, lack of CPU is seldomly a problem. If anything
your buffer underrus will come from IO bottlenecks.
Of course you can "starve" the burning process if you really want to.

But if you get a shrinking or too small buffer, it's usually the
disk not being able to seek fast enough. For example, if your source
tree has lots of small files. The seek-to-the-data of all those small
files will hurt throughput in a major way.
And even worse: If you have anohter process suddenly require that
kind of attention of the disk drive.
