Ugh... Pth is only portable on POSIX-based systems. I can't conceive how
we could port pth-based thread libraries to uKernels like L4. Hmmm....

Okay, NGPT could be a nice-to-have addition to glibc, but if it were really
added as integral part of the Hurd, the L4/Hurd port would most likely
completely fail. But I didn't examine NGPT in detail, so please don't
take this statement too seriously for now.
