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. +The switch to pthreads has been attempted multiple times, but in the past it always hit some tricky issues which proved to be a roadblock. 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 on topics like locking and memory management. 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. |
