Array pool memory stream #48

Closed mgravell closed 4 years ago

mgravell commented 4 years ago

Provides something similar to MemoryStream, but which loans memory from the array-pool; for sizes up to the pool's upper limit, this improves allocations and performance; for sizes over the pool's upper limit, it tracks MemoryStream for perf etc
