[Xcb] libX11/libxcb uses 100% CPU time after killall -3 xv / killall -2 xv (Ctrl-C)

[Barton C Massey]

Thanks hugely for the bug report!  I've managed to reproduce
the bug, at least, but I really am pretty swamped right now
and really don't have time to debug it myself.  

I note that xv makes a bunch of Xlib API calls from its
signal handler.  As far as I can recall this is technically
illegal in Xlib; furthermore I'm pretty sure it will cause
trouble in Xlib/XCB.  My guess is that the malloc pool is
getting corrupted: Xlib/XCB uses malloc pretty heavily, and
Xlib basically doesn't use it, so this may be the
difference?

Hopefully one of our other folks will take a shot at
confirming all this, please?
