Page Fault Handling, Trap Flow, and Recovery Paths: Pitfalls and Red Flags

Pitfalls and red flags

Pitfalls and Red Flags for Page Fault Handling, Trap Flow, and Recovery Paths is anchored on Fault service latency (median/P99), restart success rate, and throughput impact during demand paging and copy-on-write stress.. Convert observations into mechanism-backed decisions with explicit ownership.

• Tuning knobs without proving first failing mechanism.

• Ignoring privilege, trap, and memory-protection side effects.

• Mixing extension profiles across benchmark runs.

• Shipping on one benchmark uplift without stress replay.
