RejoinCOWPages is copying dirty pages to a new view
of the memory map.
If another thread modifies the heap between when
RejoincCOWPages copies the data and when the view is
remapped, the modification will be lost, leading to a
memory corruption.
In short, when RejoincCOWPages is running, all other
threads must be stopped.

This new command triggers a config flush to save the in-memory config to
disk. This is useful for cases of a configuration management system or a
package manager wiping out your sentinel config while the process is

for scripting a backup and migrate or clone of a running sentinel.

A way for monitoring systems to check that Sentinel is technically able
to reach the quorum and failover, using the currently visible Sentinels.
