I don't know if it's a better answer, but an alternate solution we've
been carrying around in Solaris libX11 since long before I got here is
to allow XInitThreads() to be called by other plugins/libraries even after
the X connection is up and running.    I've not checked how well it works
in the current world where half of XlibInt.c was ripped out and replaced
by xcb calls, but the code is available if someone wants to look at it.
