As implemented, there is a timeout for that loader peer based on the
amount of time it should take to request all the headers. The time
period is defined as a base time plus the number of expected headers
times an expected amount of time per header. For example, the timeout
would be 25 minutes with a base time of 15 minutes, 1 millisecond per
header and an expected 600000 headers.
