Build break fix.

Browse source 
Summary: Skip list now cannot estimate memory across allocators
consistently and hence triggers flush at different time. This breaks certain
unit tests.

The fix is to adopt key count instead of size for flush.

Test Plan: Ran test on dev box and mac (where it used to fail)
