Inspired by an off-hand comment in https://github.com/llvm/llvm-project/pull/178836#discussion_r2808955751.
To ensure code properly handles calls which can fail and provide `errno` it might make sense to implement a "fuzzer" which randomly fails such checks during execution.
The most sensible use case (and probably the one to start with) would be calls which can fail and need to be re-tried.
Possible tunables for this would be:
- the call(s) to fail
- the `errno` values to fail with
- the frequency to fail with (a percentage or interval)
