Description

jemalloc provides the ability to purge a specific arena via mallctl with the oid 'arena.[id].purge', so I was wondering if the feature closest to it would be LocalAllocator::flush() (or literally teardown in the upper level) and it was a good idea to expose such capability as C symbol ?

Research direction

Start by reading LocalAllocator::flush() and the upper-level teardown path, then compare their behavior with jemalloc's arena.[id].purge mallctl operation. Determine whether exposing this capability as a C symbol is intended and define the expected scope before identifying an implementation and validation path.
