My apologies. Terminology problem; see below.
Note that the pretimeout, as documented, is a difference to the real
timeout, not an absolute time (which I had not realized before).
"Note that the pretimeout is the number of seconds before the time
when the timeout will go off. It is not the number of seconds until
the pretimeout. So, for instance, if you set the timeout to 60 seconds
and the pretimeout to 10 seconds, the pretimeout will go off in 50
seconds. Setting a pretimeout to zero disables it."

I think I used the wrong term. I should have said something like
"two distinct timeout values".
