By "race" do you mean that xterm writes from more than one thread to
the same descriptor, which is used by Emacs as keyboard input, and the
two inputs mix up into one large mess?  If not, who is racing whom
here?

One way of finding out would be to build Emacs --with-dumping=unexec.
I'd be surprised if it turned out to be pdumper, but who knows?

Thanks.
