 Another bit of fact:  the following change to more causes it to stop
 core dumping.
 
 This should *not* be the "solution" -- there is something wrong in the
 kernel, I think, that is causing TCSADRAIN to not work for this case.
 Unfortunately, I can't reproduce it in any way that would let me run it
 under gdb -- "cat foo | ./more" doesn't do it, even though that does set up
 a pipe.
