[Media_api] portmidi crash cleanup questions

[John Stewart]

I'm looking into using portmidi.  And I quickly noticed whole pm_dll.dll 
thing being used to close devices on exit/crash.

Questions
1. The README_WIN.txt seems to imply that pm_dll.dll is the way to go.  
But a comment in pm_win.c in the pm_init function says atexit works just 
as well.  Which one is accurate?
2. Have you looked into using the SetUnhandledExceptionFilter Windows 
API function to handle shutdown in case of a crash?

I'd like to get rid of the need for the DLL if possible, but if it's the 
best way then I guess that's the way it is.

Thanks,

John Stewart
