Err...yes it does :) At least on terminals.

If this is actually caused by stdout returning EAGAIN then it wouldn't 
happen right away, it would happen whenever stdout's buffer gets full. 
Which will depend on how fast your terminal is, how big the stdout 
buffer is, how fast you are printing, etc. I don't know if there is a 
way to shrink stdout's buffer to 0, print something big, and see if you 
get EAGAIN.
