Pre-Cisco acquisition jitters - What's the impact?

With the Cisco acquisition process dragging on, I'm starting to feel a general sense of unease about job security here at Splunk. There's a lot of speculation flying around about potential restructuring or redundancies once the deal closes. I've seen some posts on other sites mentioning past layoffs, but nothing official recently. It's tough to focus on the day-to-day work when there's so much uncertainty about the future. Are people preparing their resumes? Are managers giving any hints, even subtle ones? Just trying to gauge the general sentiment and see if others are feeling this way too. Any insights would be appreciated.
