I ran this for the past two days, multiple copies to put some load on
the system (the initial problem with gettimeofday() was easier to
reproduce under load). Nothing.
So, I guess that rules out unsynced TSCs as the cause? Or perhaps it
only happens in other conditions, for some reason. I'm on holidays
right now, but my coworkers should be able to continue investigating
other possible causes.
Thanks for the advice/test program.
