Also, what about this case?

~"GNU gdb 6.1-debian\n"
~"Copyright 2004 Free Software Foundation, Inc.\n"
~"GDB is free software, covered by the GNU General Public License, and you are\n"
~"welcome to change it and/or distribute copies of it under certain conditions.\n"

~"Using host libthread_db library \"/lib/libthread_db.so.1\".\n"
~"\n"
(gdb)

Is this considered synchronous or asynchronous? I consider it
asynchronous, and I don't have any way to tell that except check to see
if the parse tree has nothing but stream messages. What do you think?
