[scruple]

I've done a lot of similar work and learned a lot of similar lessons. They were interesting and fun challenges but I've since moved on from Ruby in my professional life.

I'll say this much: When I was working on these applications, one of the minor wins that I had was swapping them over to the jemalloc memory allocator. It has introspection/instrumentation tooling that is really useful for these sorts of situations. You can use `MALLOC_CONF` [0] to trigger some built-in profiling. For instance, `export MALLOC_CONF='prof_leak:true,lg_prof_sample:0,prof_final:true'` will trigger jemalloc to log the heap at exit which is very useful for tracking down leaks.
