I'll look at it, but hopefully so will Jamey and Josh, who
are more likely to figure it out quickly than I am.  It is
almost surely an Xlib/XCB bug rather than in Xlib proper,
and it's a strange one.  Perhaps the connection isn't
getting closed properly, but I have no idea why.

(BTW, I tried to create an account on the Novell Bugzilla to
log some stuff, and after futzing around for a few minutes
with the full page of required personal information and the
onerous restrictions on logins and passwords, I just gave
up.  I'll make sure to cc you on everything I find, and you
can fight it for me. :-)
