Check for reviews hanging

[vikram6]

The "Check for reviews.." step hangs sometimes. I assume it's because it wasn't able to connect to the reviewboard server or didn't get a response back from the server. I'm not able to abort the job or send an interrupt to the thread either. The only solution was to restart the jenkins server. Here's the thread stack:
