The "Use non-blocking locks" section already explains that blocking=False makes one attempt, so the recipe keeps only the line that changed. The fragment takes the descriptive name CONTRIBUTING asks for and names the replaced approach.

The "Probe a lock before blocking on it" recipe approximated a single attempt with
timeout=0.0001. A finite timeout still polls, and a reader copying the recipe learns a workaround where the library has a flag for the case. 📝 The recipe now probes withblocking=False, the one-attempt form the guide's "Use non-blocking locks" section already documents, and the rest of the recipe (one log line on contention, a blocking wait, one balancedrelease()) is unchanged.
