Note that glibc has a similar problem in multithreaded contexts. It strands unused memory in thread-local pools, which grows your memory usage over time like a memory leak. We got lower memory usage that didn't grow over time by switching to jemalloc. Example of this: https://github.com/prestodb/presto/issues/8993 https://github.com/prestodb/presto/issues/8993
