That looks like a bug - I saw it hang in the QueryFont call when I ran
with the installed xscope 1.3.1 on my system, but running with the
local build I have here (1.3.99.901 plus the three patches I mailed
this week) let it proceed fine.   I wonder if it's related to the
BIG-REQUESTS handling bug I fixed in the meantime, or the patch a
bit earlier in git (but still post 1.3.1) from Peter Jeremy to fix
a deadlock when the server or client blocks on write.
