Although there's every chance you are right, the existing code is definitely buggy: if one of glib's fds is greater than xgselect's initial fds_lim, xgselect can inspect garbage in its masks, which can't be good. There are some other glitches there too, e.g., mask bits might not be properly cleared if pselect times out and returns zero.

Since the patch fixes bugs (even if not *this* bug) I installed it as emacs-24 bzr 116966.

And thanks, Eli, for fixing the ChangeLog entries I inadvertently nuked. I was fixing them myself but bzr is pretty slow for me. I don't know how it happened; I just edited the ChangeLog file as usual with emacs-24 Emacs.
