You can subscribe to "heap used by process is too large" events using
erlang:system_monitor/2. You can also make an educated guess based on
the code to call garbage collection at certain points in the code (for
example we have a gen_server that uses quite some memory during
initialization, but then it releases most of the memory, so we have an
explicit garbage collection at the end of the init function).
