Well, whaddya know! I never realized it was a shell script; figured it was
compiled C code (never had occasion to look at its source, so......).

I wonder if the key is in this comment from the source code:

# Shell script for seeing what the exim processes are doing. It gets rid
# of the old process log, then sends SIGUSR1 to all exim processes to get
# them to write their state to the log. Then it displays the contents of
# the log.

Could it be that the Exim process responding to SIGUSR1 writes out a console
message directly, rather than those messages coming from exiwhat itself? Is
this something that might be distro-dependent? (RH 8 is used in this instance.)
