Indeed, this was part of the problem.  Several people sent mail to the
effect that "fdopen(3c) doesn't allocate a buffer like fopen(3c)".
This is only partly true: SysVr3.2 doesn't allocate a buffer in
fopen(3c), but apparently ISC's streams/stdio interaction can require
it.

Another apparent problem is that sendmail fdopen(3c)'s a file
descriptor more than once.  I'm a little amazed this hasn't been
caught before, but I guess BSD stdio doesn't notice the problem as
long as the file descriptor isn't a regular file.  Simply dup(2)'ing
the descriptor to fdopen(3c) it helped a lot.

Thanks to Doug McCallum for providing most of the clues.
