I do agree with Julien in the sense that developers could become lazy 
and in general won't care much anymore about initializing thread support.

OTOH, if you pick a Qt application for instance, you will see that it is 
close to impossible to track from a stack trace of 80 functions whether 
XInitThreads() is called properly or not. At the same time, it's not a 
big deal to maintain the support Rami made in libX11. So why not?
