Bug ID: 57933
           Summary: SAVIHost can take a long time to close, with it and
                    wineserver eating the CPU
           Product: Wine
           Version: 7.5
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: winealsa.drv
          Assignee: wine-bugs@winehq.org

      Distribution: ---
Starting from 1fa0d491a87f5c7d9f600ea95ee2bfc37ca6f940 in Wine 7.5, SAVIhost
can take a long time to close, with it and wineserver then using the CPU a lot,
causing me to have to terminate it manually.
It seems the amount of time it can take depends on system, on my main machine
I've had it take a minute sometimes, whereas my laptop (which is much slower)
can somehow do so in up to about 10 seconds.
This still happens on Wine 10.3, which just released.

Steps to reproduce:
1. Execute "winetricks mfc90" to get a required DLL
2. Extract scva_win_trial.zip and install the Roland Sound Canvas VA VST
3. Extract savihostx64.zip, and move savihost.exe to "C:\Program
Files\Roland\Sound Canvas VA"
4. Rename savihost.exe to "Sound Canvas VA.exe"
5. Run the renamed executable
6. Go to Devices>MIDI, and set Input Port 1 to "Midi Through Port-0"
7. Close the program
(I mentioned this in passing a few years ago in 52828 but never made it its own
report, sorry)
