Occasionally, blender enters a select() with a NULL timeout, waiting for
events from the X server.  If this happens when it's inactive for a
prolonged time, autosaves get "queued up" and are processed at once when
the select finishes (due to blender getting an event).  If it has been
frozen for several days, the hundreds of autosaves will take a
significant time.

There seems to be a good amount of variation in what series of events
cause this bug to appear and what don't.  Changing workspaces appears to
be the most reliable way to see it.

In my opinion, the problem is not in the infinite-timeout select but in
the fact that blender seems to increment the next autosave time instead
of setting it to current time plus interval.

I took a look at the source and found that I was indeed correct in my  
initial analysis.  The increment happens in file  
intern/ghost/intern/GHOST_TimerManager.cpp, function  
GHOST_TimerManager::fireTimer, lines 146-149.  I don't know enough about  
the architecture to make a patch for it though.
