TTY child frame cursors behave even worse under GPM and a TERM=linux 
terminal.  In this case, the cursor ends up on some lines always 
appearing at the end of lines (ignoring separate frames or windows) and 
sometimes in the right place.  The point position is correct though and 
the cursor does appear correctly once I start pressing simple keys like 
'A'.

Unfortunately, the redisplay code in Emacs is super hard for me to 
understand and I can't figure out where or how the cursor gets 
positioned.  If someone could give me some pointers here, I'd love to 
investigate further.
