Yeah, I figured something like that.

Hm, "slow" of course is just a little test program I wrote for this purpose. 
In reality I want to call another program whose behavior I can't influence 
(well, technically I could because it's open-source, but let's assume it to 
be a black box for now).

If 'slow' or some other program does buffered output, how come I can see 
its output line-by-line in the shell?
