> These memory management function changes would set the `errno`. So when
these memory management functions are called from the OS, the `errno` may be
trashed. Kernel logic must never modifiy the `errno` value per Issue #1027.
>
> In order to make this change, the memory management subsystem architecture
will need to be modified to permit OS access to the allocators without
modifying the `errno`. For example, perhaps there is an` nx_realloc()`, for
example, that is called from `mm_realloc()` like:
>
> ```
> mem = nx_realloc(USR_HEAP, alignment, size);
> if (!mem)
> {
> set_errno(ENOMEM);
> }
> ```
I will revert errno changes and keep only zero-allocation logic, so `errno`
compliance will be handled in a separate change
