Last year, Richard Braun took up the task again and finished the transition of the Hurd libraries, glibc and libpthread to pthread. His work required significant low-level magic, including the reworking of condition implications, finding a workaround for changing the stack size, avoiding a segfault during early initialization and adjusting priorities to avoid starvation. + As followups, Thomas Schwinge [debugged and fixed](http://lists.gnu.org/archive/html/bug-hurd/2012-12/msg00044.html) a deadlock with child threads resulting from a regression due to earlier fixes, and Cyril Roelandt shared a [patch series](http://lists.gnu.org/archive/html/bug-hurd/2012-12/msg00018.html) to fix double mutex unlocking with pthreads. We will likely see more fixes like these, given that the whole threading interface changed, which will expose previously invisible bugs. Also Samuel Thibault [provided](http://lists.gnu.org/archive/html/bug-hurd/2012-12/msg00052.html) new [installation CDs](http://people.debian.org/~sthibault/hurd-i386/installer/cdimage/current) and a new [qemu image](http://people.debian.org/~sthibault/hurd-i386/). Additionally to using pthreads, these now offer keyboard layout configuration. |
