[VirtualBox] VM freezes when resumed after suspend caused by disk full

[Yuri]

I noticed this few times that when VM hits disk full and gets to suspend 
state, resuming it when disk is available leads to its freeze.
Nothing obviously wrong is in log:
00:02:01.239279 Console: VM runtime error: fatal=false, 
errorID=DevATA_DISKFULL message="Host system reported disk full. VM 
execution is suspended. You can resume after freeing some space"

00:08:30.498764 Changing the VM state from 'RESUMING' to 'RUNNING'.

Observed this with various FreeBSD guests on amd64 10-STABLE host.
