FYI

Related behavior is apparent when you have a mplayer call inside a while
read do done<filename bash loop. It sucks all the file and you don't
iterate after the first mplayer call.  kicked my butt until I asked for
help on a good shell-scripting list.  I was/am using -slave.  I don't
know if that makes a difference.
