Jason Evans	9bad079039	Refactor time_* into nstime_*. ... Use a single uint64_t in nstime_t to store nanoseconds rather than using struct timespec. This reduces fragility around conversions between long and uint64_t, especially missing casts that only cause problems on 32-bit platforms.	2016-02-21 21:39:05 -08:00

Jason Evans	243f7a0508	Implement decay-based unused dirty page purging. ... This is an alternative to the existing ratio-based unused dirty page purging, and is intended to eventually become the sole purging mechanism. Add mallctls: - opt.purge - opt.decay_time - arena.<i>.decay - arena.<i>.decay_time - arenas.decay_time - stats.arenas.<i>.decay_time This resolves #325.	2016-02-19 20:56:21 -08:00
