Uh, our systems guy who's much smarter than me noticed that it was crashing every few minutes (log below).  I think what happened was that Varnish got confused because our "persistent" file was the same as the old "file" file?

This problem went away when we removed the file and let Varnish create a new one -- but apparently it just crashed in some other way a little while later.   (I wasn't in the office today and only understood that it didn't work and they were going to switch back).

Anyway – is persistent storage considered ready for use?  It's listed as "experimental" in the man page, but I was hoping that was overly cautious since the feature has been around for a while now.  :-)
