No, I meant that you can turn off fast seek. But it turns out it's too 
far downstream to affect caching so it won't work.

Regardless, I don't see much point having a setting here. On the one 
hand, cache_read can be tested already without any new setting. On the 
other hand, neither prefetch nor cache_block can be tested effectively 
even with a forced cache:
- cache_block requires a block-based access,
- prefetch requires control on the timing of the underlying access so 
that the test cases are reproducible (*).

(*) TCP access on loopback, or file access on a FIFO might work. I am 
not sure.
