Aha! That would be why I've never seen it. I invariably run
with a fifo control pipe, a TCP control, and usually at least
one dctrl connected. Plus the syslog fd of course.
It would be better to use the close on exec flag rather than
going to all this trouble anyway. In the meantime it should be
possible to fix it by looking in shell.c for the close(0), 1, 2
which is surrounded by #if 1 ... #endif and has a FIXME comment.
Change the #if 1 to #if 0 and I suspect it might work.
