Apologies for the incomplete line here, I'll rewrite the commit
message in a subsequent patch.

I meant to say "This is to handle a case that Peter described where
the throughput of operations involving continuous I/O requests is a
victim of low-frequency and ends up getting 'stuck' in a loop as he
described in [1]."
