                           Workaround for a Heisenbug
                                        
Okay, now I'm concerned. I'm now running the production greylist daemon [1]
on an actual server (not a virtual server) with the checkpointing feature
enabled, and it's working [2]. That can mean one of two things:

  1. There's a bug in the virtual server environment that my program tickles
  2. There's a bug lurking in my code that the virtual server environment
     tickles

Neither one is good, and it's bugging me that I don't know which is the case.
But I managed to at least work around the problem in the meantime (now watch—
the bug is in my code, but it's the virtual server environment that causes
the bug to surface after a few hours instead of a week or so it might take on
a physical server).
