xinit hangs on XWin infinite loop when using -displayfd

[Matt D.]

Still hangs with the latest 1.15.1-4 release.

On my main machine, I get the following output:

$ xinit -- -displayfd 1

read display number ':0' from X server
0

On the VM it just hangs. Taskmanager shows xinit.exe waiting or hung 
with XWin.exe churning cycles and eating memory; about 4kB a tick.

Also on the VM, if I run the following:

$ xinit -- -displayfd

Then the display will open. So it seems to be an issue with whatever 
code is dealing with the file descriptors.
