Some CD-ROM/CD-R drives will add an offset to the position on

(ca. 1/75 second) on reading. So when this program queries a
specific sector, it might not receive exactly that sector, but
shifted by some amount.
Note that if ripping includes the end of the CD, this will this
cause this program to attempt to read partial sectors before or
past the known user data area of the disc, probably causing read
errors on most drives and possibly even hard lockups on some
buggy hardware.
[Note to libcdio driver hackers: make sure all CD-drivers don't
try to read outside of the stated disc boundaries.]

We can't perform cache determination timing based on looking at
average transfer times; on slow setups, the speed of a drive
reading sectors via PIO will not be reliably distinguishable from
the same drive returning data from the cache via pio. We need
something even more noticable and reliable: the seek time. It is
unlikely we'd ever see a seek latency of under ~10ms given the
synchronization requirements of a CD and the maximum possible
rotational velocity. A cache hit would always be faster, even
with PIO.
Further complicating things, we have to watch the data collection
carefully as we're not always going to be on an unloaded system,
and we even have to guard against other apps accessing the drive
(something that should never happen on purpose, but could happen
by accident). As we know in our testing when seeks should never
occur, a sudden seek-sized latency popping up in the middle of a
collection is an indication that collection is possibly invalid.
A second cause of 'spurious latency' would be media damage; if
we're consistently hitting latency on the same sector during
initial collection, may need to move past it. */
