Nate,  newer runtime uses TLS callbacks (more detailed information can
be found in pe-coff specification).  For newer OSes this support is
present. For older Windows OSes the implementation uses still the DLL
approach (mingwm10.dll). but uses here a lazy loading mechanism. The
TLS callbacks getting called for each thread/process
attaching/detaching to a process, like a DLL hook.
