/**
|
|
Returns an un-pooled `Buffer`.
|
|
|
|
In order to avoid the garbage collection overhead of creating many individually allocated Buffer instances,
|
|
by default allocations under 4KB are sliced from a single larger allocated object.
|
|
This approach improves both performance and memory usage since v8 does not need to track
|
|
and cleanup as many Persistent objects.
|
|
|
|
In the case where a developer may need to retain a small chunk of memory from a pool
|
|
for an indeterminate amount of time, it may be appropriate to create an un-pooled `Buffer` instance
|
|
using `SlowBuffer` then copy out the relevant bits.
|
|
|
|
Use of `SlowBuffer` should be used only as a last resort after a developer has observed
|
|
undue memory retention in their applications.

Allocates a new `SlowBuffer` of `size` bytes.

The `size` must be less than or equal to the value of `Buffer.kMaxLength`. Otherwise, a `RangeError` is thrown.
|
|
A zero-length Buffer will be created if size <= 0.
|
|
|
|
The underlying memory for `SlowBuffer` instances is not initialized. The contents of a newly created `SlowBuffer`
|
|
are unknown and could contain sensitive data. Use `buf.fill(0)` to initialize a `SlowBuffer` to zeroes.
