We update `shard->last_purge` on each call of `hpa_try_purge` if we purged something. This means, when `hpa_strict_min_purge_interval` option is set only one slab will be purged, because on the next call condition for too frequent purge protection `since_last_purge_ms < shard->opts.min_purge_interval_ms` will always be true. This is not an intended behaviour. Instead, we need to check `min_purge_interval_ms` once and purge as many pages as needed to satisfy requirements for `hpa_dirty_mult` option. Make possible to count number of actions performed in unit tests (purge, hugify, dehugify) instead of binary: called/not called. Extended current unit tests with cases where we need to purge more than one page for a purge phase. |

jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. jemalloc first came into use as the FreeBSD libc allocator in 2005, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications. The COPYING file contains copyright and licensing information. The INSTALL file contains information on how to configure, build, and install jemalloc. The ChangeLog file contains a brief summary of changes for each release. URL: https://jemalloc.net/
