MIRA In Memory Replay doesn't return memory after converting to rocksdb

[Gandalf-the-Grey]

start with: /home/steem/bin/steemd-0.22.x --replay --set-benchmark-interval 100000 --advanced-benchmark --memory-replay

Replay is done, sync is done, getting blocks for quite some time, but still keeps taken for in memory replay:

ps -o rssize -p `pidof /home/steem/bin/steemd-0.22.x`

  RSS
55832544

Workaround: after replay is done, stop and start again:

  RSS

seems like issue is present also without --memory-replay:

USER        PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

(after replay finished)
