eryksun added the comment: already has a warning after it introduces CDLL, OleDLL, and WinDLL:

    The Python global interpreter lock is released before 
    calling any function exported by these libraries, and 
    reacquired afterwards.

It links to the glossary entry:


It wouldn't hurt to elaborate and box this warning.

Subsequently, PyDLL is documented to *not* release the GIL. Also,  section documents that CFUNCTYPE and WINFUNCTYPE functions release the GIL and PYFUNCTYPE functions will *not* release the GIL.
