Feature or enhancement
Proposal:
In Linux 5.17 a new feature was added, PR_SET_VMA_ANON_NAME, which lets you give names to anonymous virtual memory ranges. These names are shown in /proc/<pid>/maps, which can help with debugging.
The pymalloc allocator uses mmap to allocate arenas. It should use PR_SET_VMA_ANON_NAME to give names to the memory ranges containing arenas, e.g. "Python: arena".
Some examples of this done for other languages are in Glibc and Go.
Has this already been discussed elsewhere?
This is a minor feature, which does not need previous discussion elsewhere
