Goal

When trying to make ATMI calls from a VB application through a custom wrapper DLL and via wtuxws32.dll, the VB
application crashes when exiting. The call flow is:

    VB APP -dynamic loading-> Wrapper DLL -implicit loading-> WTUXWS32.DLL -dynamic loading-> Tuxedo /WS
libraries

In the above example, dynamic loading means LoadLibrary() and implicit loading means linking the binary with the
corresponding .lib file. This seems to be tied to the way VB dynamically loads libraries. When using wtuxws32, another
level of dynamic loading is added.
