Anyone have leap second weirdness to share?
In my case, since midnight I'd noticed Firefox mysteriously using 100% CPU.
Verified on both my computers, across Firefox versions.
Running an strace didn't give me any useful info ...
Even blocking network access made no difference.
I tried other browsers. Some also used 100% CPU ( galeon, chromium ) and others did not ( surf, epiphany ).
Then I start reading over recent Slashdot news articles
... and catch a glimpse of a torrentfreak
story about Leap Second glitches ... suddenly it all makes sense.
After updating my system and rebooting, the problem has gone away. ^_^
