Remove all timers and other debugging logs except for the one timer on pcache1TruncateUnsafe(). (check-in: 5980e625 user: drh tags: debug)

11:44
Add another timer on pcache1TruncateUnsafe(). (check-in: 42ce53f6 user: drh tags: debug)
11:23

Use __sync_synchronous(), when available, instead of a mutex when a memory barrier is needed. (check-in: 7d4562e9 user: drh tags: debug)
14:10
Add calls to sqlite3_log() when sqlite3_mutex_enter() takes more than 100,000 CPU cycles. (check-in: 33c7ef7a user: drh tags: debug)
