vm0 and vm1 are peers, each holds a DR. Let P and R have the same RVV and RVVGC: P7,R6, RVVGC
is P0,R0. vm1 becomes offline then restarts. Use testHook to pause the GII, then do tombstone
GC triggered by expireBatch (not by forceGC) at R only. The tombstone GC will not be executed
at R
because R's region is not initialized. Tombstone GC is ignored at P because GII is on-going.
The deltaGII should send nothing to R since the RVVs are the same.
