POSIX semaphores should be fixed in 8-CURRENT, pending MFC. There are rtld + malloc issues in FreeBSD. Python multiprocessing's use of POSIX threads is not strictly POSIX compliant, as it tries to do a lot more than just call exec() or async-signal-safe POSIX APIs after fork()-ing. There is a degree of reluctance in the camp to fix for these reasons... In the meantime, you may wish to try building Python 2.6 on FreeBSD using GNU Pth, here is a patch: http://people.freebsd.org/~bms/dump/python26-fbsd-pth.patch thanks! BMS
