I don't know what qemu is nor what it does when it claims do a "grab".
But regular X grabs behave the way I described above.  If they aren't
released when the connection closes chances are something else is going
on.  I know this is getting old, but you don't happen to have a link to
a bug report where this is discussed?

No.  What surprises me is when people are fine with those bugs as long
as there is a quick way to kill the X server that is enabled by default.
