Don't fear. Measure :-)

Doesn't sound outrageous to line-buffer your output to file.

The output to screen is already line-buffered (by default,
at least) and isn't killing you, so if I were you, I'd set
up a benchmark run and torture things a bit. Then, *if* you
notice any whiff of a problem, you could try a more clever
scheme like timeout based flush to better get hold of bursts
(if I understood your description, things go out in bursts).
