   @jayzhan211 @mbutrovich could you take a look when you have time? Semi/anti 
sort-merge joins charge each buffered key-group slice for its whole parent 
batch, so the reservation can run well above the memory actually held and fail 
allocations under a tight pool. This charges only the rows the slice holds. It 
is independent of #25986 and does not conflict with it.
