Do you use FreeBSD on a regular basis? Then you might want to know that Poul-Henning Kamp is asking for donations to complete various I/O related projects by the end of the year (instead of by sometime in the next two years).
Poul certainly has the chops. He's been committing since FreeBSD 2.0, about ten years ago. You may have found some of his papers on FreeBSD in src/share/doc/papers.
