Comment (by SergeyBiryukov):

 Replying to [comment:90 SergeyBiryukov]:
 > Yes, in my testing using the steps from comment:19 (with Redis instead
 of Memcached), the base install appears to be unaffected, the issue only
 occurs when using persistent cache, which does handle the `$force`
 parameter.

 Just noting that this is similar to what [source:tags/5.3/src/wp-
 cron.php?marks=68#L47 _get_cron_lock()] is doing to retrieve the cron
 lock.

 That appears to be the only other usage of `wp_cache_get()`'s `$force`
 parameter in core so far, introduced in [18659]. It's a bit different in
 that it also performs a DB query if not `wp_using_ext_object_cache()`.
 Looks like that's not necessary here.
