The fact is that SDL video API calls should be performed on the main thread,
the fact it may work if something else doesn't occur it may be true on
windows but not on other archs or with other versions of SDL, I suggest you
to build a SDL userevent in your thread and let the main thread perform the
Flip call in his loop.
Also be sure to use software surfaces, otherwise in HW surfaces "pixels" can
be null if surface is not locked, and you cannot lock a surface if you are
not the video thread owner...
