TempAlloc: Request for Review For Inclusion in core.memory

[Andrej Mitrovic]

Ok, perhaps you should put a note in the docs about falling back to
the C heap. Or maybe that's just common sense for people in the
know-how?

I've realized the allocation attempt was actually quite a bit more
than 500Mb. The C lib returned the number of channels and frame count,
which totalled to a frame count of 291_335_184. Multiply that by the
float size (4), and you get: 1_165_340_736, or 1.65 GB.

The GC heap can actually allocate even 200_000_000 elements on my
system, so that's around 800MB if I'm right.
