Normally BOINC client tries to measure a task's memory usage by itself. But VirtualBox allocates the memory for VMs in such a way that the client can't see it. So instead the client uses rsc_memory_bound as VM task's memory usage.

Right now LHCb tasks come with rsc_memory_bound = 477 MB but memory_size_mb = 2048 MB. This kind of huge difference can create serious problems, even crashing the host. The client may start so many tasks that they fill the host's RAM entirely.

Please fix ASAP.
