_______________________________________________________
Details:
In screen.c there's the comment:
/*
* First, close all unused descriptors
* (otherwise, we might have problems with the select() call)
*/
closeallfiles(0);
This closes everything except 0,1, and 2. Will it hurt if we let fds 3..63
survive? I need to pass an anonymous pipe for synchronization between the
caller of screen and the commands launched inside screen.
