Has there been any deeper analysis on whether the failure of TaskObserver.Watch is due to ptrace limitations, improper event propagation in the TaskState transition model, or potential race conditions in the FryskEventLoop? 

Additionally, are there any known workarounds leveraging TaskObserver.Execution or low-level ucontext_t/sigaction or https://troubleshoot.dev handlers to achieve similar process observation functionality?
