/** Attempts to clear the given blob of memory.

|

The underlying implementation of this function takes pains to
|
|
attempt to outsmart the compiler from optimizing the clearing
|
|
away. Please note that, despite that, remnants of content may
|
|
remain floating around in memory as well as registers, caches
|
|
and more.
