title: Is jemalloc heap profiling tracking allocations only?
body: <p>I'm trying to solve some memory leaks, and I'm using jemalloc to dump heap profiles:
  <code>MALLOC_CONF=prof:true,lg_prof_interval:30,lg_prof_sample:17</code></p>
  
  <p>Works as charm, but I don't know what I'm looking at :)</p>
  
  <p>Does jemaloc <a href="https://github.com/jemalloc/jemalloc/wiki/Use-Case:-Heap-Profiling" rel="nofollow noreferrer">heap profiling</a> show all (sampled) allocations, or just the ones that haven't been free()-ed at the moment of taking a dump? Or to put it differently: is it an allocation profile, or "live" blocks profile?</p>
