This is just an ancient bug on my part.  I've made the appropriate
changes and will check them in once they are tested a bit.

I am wondering whether this is some bad interaction between Scheme and
AFS.  Julie, all of these rmail files are in your home directory at
csail, right?  If so, then they're stored in AFS.

The reason I'm thinking this is that AFS is known to have problems
with certain kinds of file-system transactions.  Subversion, for
example, is prone to corruption under some circumstances.

Of course, it could just be a bug in the error handling when the rmail
file is written.  Or it might be a deeper bug where the file-output
code doesn't properly flush the output buffer; but I'd expect to see
other evidence of that.

Julie, how big are the rmail files in question?  I'd like to know the
exact number of bytes, both truncated and whole, for any samples you
have.  That might give me some insight into the problem --
specifically if the truncated file is a multiple of 4096.
