I am running a small Julia webapp on Heroku. The machine on which Julia is running would report that report 60GB total memory and 5GB gree.

```bash
 $ free -g 
             total used free shared buffers cached
Mem: 60 54 5 0 2 11
-/+ buffers/cache: 40 19
Swap: 60 1 59

```

However, Heroku would start giving errors if my app consumes more that 1GB. Julia wouldn’t know that. I strong suspect that it does not do any garbage collection on the assumption that plenty of memory is available. Is there a way to tell Julia’s GC that it should run within some memory budget?
