Hope so too. He will be back soon. He has at the moment some sabbatical time.

Right, performance is here for sure a second issue. The major thing
for me is about pthread-w32 project, that it is slowly maintained
(yes, there are patches pending over two years for review), the
license issue about LGPL (which forces redistributable applications to
use shared version), and the speed impact. Well, latter isn't a such
big thing here IMHO, but well, I admit that native win32 threading API
is faster.
