| Simple "secured" memory management.
|
| In future it might be an idea to call the lua garbage collecter in case memory allocation
| fails. However on Linux it's a mood point since practically a NULL is only returned
| when requesting a way too large memory block the system can ever handle, if the kernel
| runs out of memory it goes instead into oom-killer mode.
