[Bug 1019708] Re: Firefox pegs CPU usage immediately, even in safe mode

This bad behavior seems to have been caused by issues with futex system
calls.  Here's the most detailed description I've seen so far, including
a small test program that can be used to replicate the behavior (I
haven't tried it since it modifies the system time):


Rather than rebooting, simply setting the system time manually or
finding some other way to call settimeofday() would have also restored
normal behavior.
