Lately, probably not.  But (Gerd and) I spent a lot of time
tracking down two bugs with it during (and just before) the Emacs-21
pretest period.  And I'm sure there are some left, although
their occurrence is rare enough that we don't notice them.

But as I said, another problem is the fact that some improvements
are harder to implement because of the restriction about what can be
done from within XTread_socket.
