[Media_api] Did Microsoft fix the bug where an open MIDI input crashes Windows?

In testing recent portmidi changes on Windows, I crashed programs with 
open MIDI input devices a number of times. In the past, this would 
almost inevitably require a reboot, but I haven't rebooted once in 
recent testing. This is a pretty strong indication that Microsoft fixed 
their serious security hole (any user could crash the host OS). If so, 
then there is no reason to include the pm_dll.dll, which is only there 
to make a last-ditch effort to close input ports when a program exits. 
This would simplify configuration and installation, but I didn't want to 
be too hasty -- after all, this bug survived for years in WinNT, Win2K, 
and WinXP. Is it really gone?
