* eval.c (rb_thread_save_context, rb_thread_restore_context):
sandbox hook to save and restore sandbox state. * eval.c (thread_no_ensure): added THREAD_NO_ENSURE thread flag. * eval.c (rb_thread_kill_bang): Thread#kill! uses the above flag to circumvent ensure, in order to prevent endless loops. [ruby-core:08768] * eval.c (rb_thread_kill): fix Thread#kill docs, which returns the thread object in all cases. * node.h: expose the rb_jmpbuf_t and rb_thread_t structs, along with the thread flags. used by the sandbox extension. * ruby.h: extern rb_eThreadError, so sandbox can swap it. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_1_8@11000 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
