Description

Presently, MemoryManager.Brk only enforces RLIMIT_DATA for the heap because .data and .bss information isn't plumbed from the loader.

Contributor guide

Research direction
Investigate the loader to find where .data and .bss segment sizes are available, then modify MemoryManager.Brk to include those sizes when checking RLIMIT DATA.
