Additional info:
I've attached a (merged) output from a 'strace -Dttffo tmp/strace/google/google-chrome / google-chrome' command. (This was run from a "root" terminal window since the google-sandbox will not run under strace.) I was away from my system for a while, and, when I returned, I terminated the (still hung) strace command with a ^C. Lokking at the tail of the output, you can see the four processes that were still open.)

Note: I suspect that this a kernel issue since it works when I boot with the 3.18.0.rc0.git6.1 kernel, even after several full upgrades of my rawhide system (now using 3.18.0-0.rc1.git2.1.fc22.x86_64) so the only binary difference between the failing and running Google Chrome application is the booted kernel.

I also noticed that, even after terminating the Google Chrome command, the 4377 process (/opt/google/chrome/chrome-sandbox /opt/google/chrome/chrome --type=zygote) is still active.

I suspect that the google-sandbox program is not compatable with a change made after 3.18.0.rc0.git6.1, but I'm not able to do much more than suggest the possibility.
