Yes, it appears `oversize_threshold` and `junk` are read only. However, from my understanding of the jemalloc docs, we can still set those after startup via the `MALLOC_CONF` environment variable as long as that variable is set before we make any call to the malloc library. > Once, when the first call is made to one of the memory allocation routines, the allocator initializes its internals based in part on various options that can be specified at compile- or run-time. -- This is an automated message from the Apache Git Service.
