When we the pipe with wsd is closed we
assume wsd has died and we terminate too.
WSD can fork us anew, if it's still alive.

The overall hit-rate improves significantly
when we don't remove entries too soon.
Here we give entries more time to show their
merrit.
There are now two limits, soft and hard.
The former is used to remove entries with no
hits at all, while the latter is used to
avoid overflowing the cache footprint too
much. Entries also get started with a single
hit, which prevents them getting evicted
too soon (i.e. right after getting added).
Finally, there is no longer need to reduce
the hit count of entries too agressively
since we have two tiers (soft and hard limits)
and zero-hit entries are removed before others.
The average cache size while auto-typing in
Writer doc is less than 180kb, which is 1.4x
the original size of 128kb.
