A networking application misbehaves and causes 100% CPU usage in wineserver
since commit 414b31bc0bbbfe005e90a1946a649082dc303c55 so it is a regression.
Reverting commits 414b31bc0bbbfe005e90a1946a649082dc303c55 and
1ccab719ee6e87b7399876d4d5b30eb889c49e32 makes it working again.

The setup is complex, but I'll try to provide useful information, testing and
extract a minimal reproducible setup eventually.
