That was the case for version 2.2.

It was due to some stupid coding. Now the filemap bits are allocated
dynamically.

It was important to have a conservative estimate. If the average was
too high, then you could run out of numbers. But it was never
important to have it really accurate. Changing the average from 13KB
to 8KB for a 30GB cache uses an additional 200KB of RAM. Not hugely
significant.
