   Yikes!  What version, i.e. snapshot date, of Scheme was this happening
   with?

Here's what it says today.
Presumably it was the same yesterday:

 Release 7.7.90.+ || Microcode 15.1 || Runtime 15.7 || SF 4.41
 LIAR/i386 4.118  || Edwin 3.116    || SOS 1.8      || IMAIL 1.21


   Also, did you have the file folder open in the same Scheme
   instance while you were doing the appending?

Hmmm... I really can't remember for sure.  I think I didn't,
but I don't know.


   My initial wild guess is either unreported memory exhaustion (which
   with Edwin as of about a year ago shouldn't be happening so much) or a
   failure appending to an already open file folder (which I spot a bug
   in, but not one that should affect this).  However, I'm just grasping
   at straws.  Ideally there would be a reproducible test case that I
   could try myself, but that's probably too optimistic...

Indeed.


I hadn't realized that when imail modifies an rmail-style file
it writes all over the old, stored messages, like this:

1, edited,, g4g8,
Summary-line: 25-Mar   address@hidden  [69] address@hidden: G4G8 Last Minute 
Info for Speakers]
X-IMAIL-INTERNAL-TIME: Tue, 25 Mar 2008 09:59:02 -0400
Summary-line: 25-Mar   address@hidden  [69] address@hidden: G4G8 Last Minute 
Info for Speakers]

So indeed there's potential to mess something up.  Or maybe
it's a bug in afs.

Here's the boundary area in the file, showing the end of the truncated
part and the start of the appended new messages:

[...everything fine in here...but message cuts off below in mid sentence]

Probably doesn't hurt to broach the idea to Jack, but not in such a way as=
 to make it an offer so there
