* parse.y (dsym): :"symbol string" style should not contain `\0'.
* process.c (proc_detach): new method Proc#detach(pid) which create background watcher thread to issue waitpid. [new] * process.c (rb_detach_process): utility function to detach process from C code. * ext/pty/pty.c (pty_finalize_syswait): terminate watcher thread, and detach child process (by creating new idle waitpid watcher thread). * ext/pty/pty.c (pty_syswait): may lost signal stopped child. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@3561 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
