Or sometimes:

chardev: opening backend "stdio" failed
qemu: could not open serial device 'stdio': Success

(!)

So what seems to be happening here is there is an implicit monitor
being set up which grabs stdio.  Because:

  #define STDIO_MAX_CLIENTS 1

my own -serial stdio option subsequently fails.  This is a regression
over previous behaviour.  I didn't specify a monitor device, because I
don't want one, and previous versions of qemu didn't give me one in
nographic mode.
