The problem is how?  The hook is called via the shared library's init
section, which knows nothing about ClassLoaders.  It is only used
while the dlopen is actually running, not while classes are loaded.
Access to the hook must be synchornized, as the comment says.

Yes, that's the point.  However, we can't have multiple class loaders
being *initialized* or more specifically calling dlopen at the same time.
