[Linux] wineserver64 and remotevstplugin32.exe.so consume all ram

### Bug Summary
the processes `wineserver64` and `remotevstplugin32.exe.so` both eventually consume massive amounts of ram, even when LMMS is closed.

#### Steps to reproduce
Load in a vst.
Close LMMS.
Monitor the processes memory usage.

#### Expected behavior
Both processes keep their usage low and exit when LMMS is closed.

#### Actual behavior
Both processes consume ever-increasing amounts of ram and stay open.

#### Affected LMMS versions
1.3.0-alpha.1.90+g2f17c0da2, master branch

Start by reproducing the reported behavior on Linux: load a VST in LMMS, close LMMS, and monitor wineserver64 and remotevstplugin32.exe.so. Done means both processes stop after LMMS closes and no longer consume steadily increasing memory.
