RefCell to reuse buffer during insertion when only have Shared Reference (&T) #4
Description
- Location: CountL2HH
- Explanation:
- CountL2HH have a function that perform "insertion and query"
- Used by UnivMon insertion, which will potentially allocate small buffer repeatedly (query a CS will need get median, which usually requires a Vec or something similar)
- Scope: UnivMon only at this moment
- Possible drawback: concurrency scaling
