Funny I woke up after just 5 houres of sleep (I was babysitting the 7 years old son of one of my friends, while she and her sis where out partying yesterday night (it was OK, he was just sleeping, so I could sit and hack on Nix and my font without any problems))... And totally awake! At this time! Whoa! And now I actually found that stupid nixPoll() bug (basically a copy-paste-error), so modulo that nixReadLine returrns the newline-character at the end of the string for some non-obvious reason, the Pipe test passes... 4 tests passed, 16 more to go...
