The in body focusing motor aught to draw more than enough current to
make the camera body hot.

This is a rather curious reply. What source, other than the battery,
is going to make the camera hot? If you are saying that the battery
was not hot when you took it out, but the camera was, then I can only
postulate that (since you said the camera was discharged) that your
timing was such that the battery itself (the source of the heat) was
no longer outputting heat but that the camera was still
storing/dissipating the heat that had come from the battery.
Irregardless of that battery appearing to recharge again, I would toss
it in the trash. It is clearly failing. Even if the battery was the
not the source of the heat ( I would wager it WAS) lithium ion
batteries hate heat and is it effectively "toast".
The overheating problem of lithium ion batteries is a known problem,
but relatively rare (hence few others with your experience).

It was likely that the camera was locked up in some non-standard mode
where motors were powered inappropriately. For instance if the SR
circuit was malfunctioning the current drawn would likely be within
the spec of the battery but the SR system may not be able to
adequately dissipate the heat developed due to the fault.

If the battery inside the camera was discharging at an excessive rate,
would that cause the camera to overheat?
