This is a bug in Exim. Looking at the code, I'm rather shocked that
it has never bitten us before now.

I'm not convinced this is correct, since at the point in the code where the
panic occurs, Exim believes it is writing to a disk file and short writes
should not occur.
Artem, can you reproduce the bug when running Exim under ktrace -di and/or
with the patch to log.c below? The st_mode value might tell us something
interesting.
Agreed -- I think the important question to answer here is whether the
descriptor being written to is a file or not. It looks like there are paths
where stderr, for example, can end up being written to -- which might well be
a pipe/socket/fifo and hence legitimately get EINTR, making this an Exim bug.
Or it might be a file, in which case most likely we're looking at a file
system bug, which we need to track down and fix.
