Virtualbox consumes very high cpu after host suspend (macos host, ubuntu client)

[Declan McGrath]

Note: I *think* this used to happened when I used Ubuntu as the host as well. Though I never tested the workaround with that combination.

1. Macos (El Capitan) host, Ubuntu running XFCE guest with xscreensaver configured as the screensaver

2. Lock Macos host (Cmd-Shift-Power Off)

3. Leave long enough for the guest's xscreensaver to kick in

4. Virtualbox reports about 150% cpu in the MacOS Task Manager.

5. After careful experimentation, I discovered that this was due xscreensaver kicking in when I had been away

Tip: You can short-circuit steps 2 and 3 by running "xscreensaver-command -activate" in the guest OS.

is this still a problem?
does it happen with the official virtualbox?
what are the host-guest virtualbox/OS versions?
