I think i can rule this out.  All of the systems which have xhost access
also have physical access limited.  There's only two other grad students
who would have the knowledge to do this, and popping up naked women
would be moe their style (mouse-down, upp thre, mouse-up would not seem
to be a high-payoff prank, anyway; unlikely to be even noticed).

also, noone has access (at all) to start a process on this machine; even
with the host issue, could they still write?
