## Memory

### `jemalloc_background_thread`

Enable jemalloc's background purge threads so freed memory is returned to the OS after bursts of large allocations, instead of accumulating as retained dirty pages. Equivalent to setting the `_RJEM_MALLOC_CONF=background_thread:true` environment variable, without requiring it.

Has no effect on builds where jemalloc is not the active allocator (e.g. `msvc`).

Default: **`false`** (disabled)
