------------------------------------
>From all my experiences, native resources should always be guarded by a safe
>net or similar no matter whether resource-cleanup is active or not. Otherwise
>leaking is leaked. It is extremely hard to figure out and debug this kind of
>issues.
> Remove GC cleaner mechanism for unsafe memory segments
