Yes. Basically every global variable in GTK assumes this. Or nearly
every one.

Erwann is working on multiple display support, which will allow
connections to more than one X display. But you're still looking at
the fairly limited thread-safety model of GTK itself.

Without knowing more details on why you have this per-thread X
connection requirement, it's hard to tell you what would be required
to meet it. What are you trying to achieve? Multiple display support?
