[SDL] SDL_thread

[Uriah Liggett]

Hello,
  Can someone tell me about how the creation of a thread using SDL_thread 
compares in speed to something like an add or a function call?  Is it 
magnitudes higher, or multiple magnitudes?  Would it be feasible to have a 
threads creating and destroying every redraw in an OpenGL application, if 
they were doing the geometry interpolation (over 25,000 triangles each 
draw).  Would it be better to just have set threads that always exist, and 
only wake up when I set a global variable to tell it to work on a certain 
piece of data?  That way there's little to no thread creation/deletion 
overhead.

Thanks ahead of time.
