Well, 0.4.5 did fix the problem I was having.  It successfully completes
the 4-way handshake now, every time I've tried it.

That's without turning debug off, too.  However, on system startup, I
had to turn it off, because on the machine I tested it on, there seemed
to be a race between wpa_supplicant and DHCP, or something.  Turning
debug off helped a lot (but didn't quite totally fix the problem;
netlogon still starts a little too early).  But I'll be looking into
that a lot more tomorrow; I think it has something to do with the DHCP

Anyway, the one thing I would like to know for sure is, after the
CTRL-EVENT-CONNECTED string gets sent to all connected frontends, should
the machine be able to pass network traffic?  (I.e., am I watching for
the right string from wpa_supplicant?)  If not, is there something else
that I should be watching for that signals when the card is capable of
using the network?
