Support Python 3.9, 3.10, 3.11, …

[autumnjolitz]

Environments to patch:

• Python 3.8 ✅
• Python 3.9 ✅
• Python 3.10 🔲
• Python 3.11 🔲

Todos:

• examine multi-process memory image coherency ✅
  • A: if the file descriptor is mmap(2)ed with MAP_SHARED, the same page cache will be used for reads/writes. If you’re using shm_open(2), it’s highly probable you’re using mmap(2) with MAP_SHARED.
• Add multi-Python version support to CI
• Add tasks.py (Invoke) for build, deploy, test actions ✅

Methodology:

1. review the code for the glibc version
2. patch references of /dev/shm to an alternate prefix
3. Add early jmps to init functions to set the alternate prefix (glibc likes to set hidden read only static variables and zero intiailized .bss globals)
4. Pass tests by being able to run the test lambda handler with a limited user.
5. Check in with the source image sha256 reference to assure image stability.
