(cygthread::terminate_thread): Eliminat racy code which reset ev and thread_sync. Remove a few nonsensical inuse checks. Exit at the bottom. (cygthread::detach): Rewrite to again try to ensure that we don't say we're signalled when we are not signalled. * fhandler.cc (fhandler_base::raw_read): Revert to signalling read success quickly. * pipe.cc (fhandler_pipe::close): Use base method to close handle. * sigproc.h (WAIT_SIG_PRIORITY): Just trundle along at normal priority to allow the pipe thread to do its thing if possible. * pinfo.h (pinfo::zap_cwd): Declare new function. (pinfo::zap_cwd): Move 'cd out of the way code' here. (pinfo::exit): Use it here. * spawn.cc (spawn_guts): And here.
