I would like to know when exactly the pid file vanishes.

A possible idea would be to have a cron job running every ten minutes:

#!/bin/bash

LOGFILE="/var/log/exim4/pidwatch.log.$(date +%Y%m%e)"
PIDDIR="/var/run/exim4"

date "+%Y-%m-%e %H:%M:%S" >> $LOGFILE
ls -li $PIDDIR >> $LOGFILE
for file in $(ls $PIDDIR 2>/dev/null); do
  echo $file >> $LOGFILE
  head -n 2 $PIDDIR/$file >> $LOGFILE
done
echo -e "\n" >> $LOGFILE

Greetings
Marc
