The issue seems specific to gnuplot under particular conditions.
See below.

Now, I can reproduce the bug on my other machine. I upgraded some
packages, and I don't know whether this is related (only pango1.0
packages seem related).

This can be reproduced with the following script:

#!/bin/sh

gnuplot -persist <<EOF
plot '-' using 1:2 t '' with line
0 0
10 10
e
EOF

No issues with GNUTERM=qt, but with GNUTERM=wxt, it doesn't work.

I suspect a race condition, as using strace makes the problem
disappear. Using ssh (even "ssh localhost", then the test script)
also makes the problem disappear.

If I destroy the window, the "gnuplot -persist" process remains.
