There is a very simple solution to that problem which I implemented 
quite a while ago: Simply make a platform-specific version of 
signalSemaphoreWithIndex (in the Win32 VM that version is found in 
sqWin32Window.c under the name of synchronizedSignalSemaphoreWithIndex) 
and override the function in the VM proxy. Simple and direct.
