Comment (by svenpanne):

 Even the warning when using GHCi 7.10.3/8.0.1 looks a bit scary: Some GLUT
 code doesn't seem to be running in the main OS thread, although the
 example code doesn't involve any multithreading. GHCi shouldn't do these
 secret thread migrations: Apart from GLUT and OpenGL there are surely a
 lot of other libraries/frameworks out there which don't like such a
 thing...
