Actually, the comment in uzbl is:
/* We don't really need to write to the file, but if we open the file as
* 'r' we will block here, waiting for a writer to open the file. */
GIOChannel *chan = g_io_channel_new_file (path, "r+", &error);
so it does block. Whether tmux should block for save-buffer or not is up
to Nick, but I don't think it'd be a good default (what do you do if the
FIFO is deleted and the reader dies? Poke around in /proc?).
