Xv man pages: http://www.xfree86.org/4.2.1/Xv.3.html
Xv specification for adapter drivers:
http://www.xfree86.org/current/DESIGN16.html
VMware Xv implementation:
http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-vmware.git;a=blob;hb=HEAD;f=src/vmwarevideo.c

Theoretically it is possible to have more than 1 video port.
The attributes are port/video specific and it is application's
responsibility to obtain the required lock before setting a port
attribute.
XLockDisplay() I think.

I meant release for users.
