Multi-threaded output

[Steven Seeger]

I am writing a multi-threaded ncurses program. The user can type in some
text fields in one window while a timed thread updated values in another
window. Sometimes the user's input corrupts the screen, however.

I notice that if I draw something and then call abort() the program quits
without updating the screen. This tells me that the output is not
synchronous. All curses calls lock a mutex via a macro which I have
confirmed works correctly. Are there any known issues with multi-threaded
ncurses?

I did notice that only the calling thread can use getch().
