vagrant spiking CPU after laptop suspend

[Jeff Abrahamson]

When my laptop awakes from suspend, vagrant spikes the CPU. I'm not able to connect by ssh at this point and existing ssh sessions to the guest fail to connect. I have to halt the guest.

Doing a vagrant up (without further provisioning) succeeds.

Because I can't connect to the badly-behaving guest, I haven't been able to debug this at all.
