I am pretty sure it works in the Windows VM. You should get multiple  
keyDown events but a single keyUp:

Down ... (pause) ... down - down - down - down - down - up.

The problem is that from the X11 VM you get this:

Down ... (pause) ... up down - up down - up down - up down - up.

Now, the up and down events bear the same time stamp (they are  
synthesized together) so the VM could actually filter out the  
unwanted up events, but it does not (yet anyway). Also, you do not  
get events for all keys like Shift etc. (IIRC only Windows gets that  

It's a shame to admit this is still not working ...
