gc: don't re-open cache so often · 415f564e

Vladimír Čunát authored Feb 24, 2020

Re-opening the cache causes fsync - every interval (1s by default).
Normally that isn't noticeable, but on encrypted ZFS it causes
high CPU consumption (even when "idle").

grahamc first reported this and Mic92 tested the patch helps. Thanks!
