Yes, you can do a similar thing with jemalloc. Take a look at the manual page,
in particular:
http://www.canonware.com/download/jemalloc/jemalloc-latest/doc/jemalloc.html#arena.i.purge
http://www.canonware.com/download/jemalloc/jemalloc-latest/doc/jemalloc.html#thread.tcache.flush
There are numerous other approaches that may be more appropriate for your
application, so it's worth skimming the entire manual page for ideas.
