pyGLFW: OpenGL version check crashes for frozen executables like PyInstaller/cxFreeze

When running the following script under PyInstaller, trying to import glfw causes an infinite loop while trying to determine the imported OpenGL library version:

Context:

• Bug report re PyInstaller
• Code in GLFW causing the issue

Please rework the check in a way that is compatible with PyInstaller/cxFreeze so programs using GLFW can be packaged properly.

AFAICS, it should be possible to rewrite this code transparently using the multiprocessing module (and a fork context), which also should simplify returning the retrieved values back to the caller.
