Well before anyone else jumps all over this, so far my tests are showing
that it does not appear to be happening in 7.10.8.

We had standardized on some very slightly modified 7.9.8 code and that
version is where I am seeing these issues. Further testing with 7.9.8
shows that every once in awhile easy_perform will return almost as soon as
the cable is unplugged with an error 18 PARTIAL_FILE as well.

It might be time to just bite the bullet and upgrade to the latest release
across the board, unless this rings a bell with anyone on something easy
that could be retrofit into 7.9.8. Other than this 7.9.8 has been plugging
away just fine so we've just stayed at that version to avoid large bouts of
regression testing.....

The select() in lib/transfer.c features a one second time-out.

If it times out, or if there is data to read/write, it calls
Curl_readwrite().

In the end of the Curl_readwrite() function, it calls Curl_pgrsUpdate()
which
handles the progress meter/callback.

I can't see why you experience these times. :-(
