In python/2.7.6/reference/simple_stmts.html#index-22, "print" is described in
terms of a "write" for each object, and a "write" for the separators. There is
no mention of locking.
On that basis, I would find the interleaving described normal and expected. And
certainly not "broken".
Just use a lock! And rebind "print"! Or use the logging system!
