I didn't find a PR, but there was at least some discussion when I added the pkgsrc Python fix, starting here: http://mail-index.netbsd.org/current-users/2012/08/15/msg020907.html While I don't think that it causes these problems, an obvious deficiency is that our kernel semaphores get inherited to child processes, while Posix says that they should be closed on exec. best regards Matthias ------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------ Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
