@michaelandrepearce Good points: paging (the consuming side) , this PR and
a mapped journal should contend the OS page cache , so it depends on the
dirty/dirty background ratio and total system memory.
Probably should makes sense to allow this feature to be configurable (and
paging as well) in order to avoid contention between them or just tune the OS
according (tricky IMO). Wdyt?
