Iterate over the lines of a string
...ry fast ways; putting strings together by programming at a very low level (esp. by loops of += of very small pieces) can be quite slow.
Edit: added @Jacob's proposal, slightly modified to give the same results as the others (trailing blanks on a line are kept), i.e.:

Difference between Bridge pattern and Adapter pattern
...called it "pseudo-remotely". This often times caused performance problems (esp. when really called over the wire).
