I'm getting a segfault on exit after logging this to syslog:

Exiting due to internal error: Failed in select: Invalid argument
kernel: pid 87513 (radiusd), uid 133: exited on signal 11

select(2) indicates that EINVAL is returned when the timeout is invalid
(being negative or too large). I modified the error message to include
the value of "when" in lib/event.c. I then got:

Exiting due to internal error: Failed in select: Invalid argument: wake
4sec, 1000000usec

I suspected that tv_usec needs to be < USEC, so I kluged the code to
subtract 1 from when.tv_usec if it's >= USEC. So far, I haven't had any
more crashes.

Commit d8084182 seems to be when this code was changed last, and I
didn't have this problem before on 2.1.x.
