xquartz: Ensure we call into TIS on the main thread
There is a place where this code was called on the main thread.
We're using a rather nasty anti-pattern to just call a block inline rather
than synchonously calling it on the main thread if we're already on the main
thread. This code could use a good overhaul, but I don't have time to rip
it apart right now. This will address the immediate issue.
