Well, I authorized lmtpd to run on localhost:30000, and used the more
stable socket(1) program to connect to it. It worked great. Apparently,
ucspi-ipc needs a bit o' tweakin to compile correctly on modern Linux. I
didn't have any problems from the command line, but Exim would deliver
the message in LMTP, pass the QUIT command, and then ipcconnect-io would
freeze, and I do mean kill -9 freeze. (Exim would thereupon declare the
message successfully delivered, which, to lmtpd, it was.)

Hmm. A bit more efficient, I think. :-)
