get_some_data(paramThingy) = 
    SomeActor ! {self(), {get_stuff, paramThingy},
    receive 
        {From, Res} -> Res
    end.
```

%% client code deals with interface paramThingy -> resultType. Simple / complicated / hierarchical / fault tolerant processing via messages is done underneath. But client code can deal with the api without knowing all messaging nitty - gritty. Since it's all async, and Erlang does selective receive, this "blocking" (it's really non-blocking async) code isn't problematic.

Tried:
Distros: Ubuntu 15.10, Linux Mint, Arch.

1. With BIOS SATA Operation = Raid: Nothing booted. Live USB boot for ubuntu started, but then stalled.
2. With SATA Operation = AHCI: 
  Ubuntu: Booted "Try Install" with nomodeset in grub. Installation started, and never finishes. Gets quite far.
  Arch: Won't boot.
  Linux Mint: Try mode installer boots, but can't see hard drive, and no network to get drivers.
3. With SATA Operation = Disabled:
  Ubuntu installs. Synaptics touchpad doesn't work. Machine runs hot, and 81Wh battery depletes in under three hours.

1. Large array (yes, allocate. unmanaged mem can work even better, but ok with managed).
2. Have a "marker" for each writer and each reader. 
3. Treat array as a circular buffer. Writers write messages and progress write marker. Up to the point where array size isn't filled.
4. Readers read till there are messages.
5. Have a reader for each handler. Each handler reads all written messages, but processes those that match criterion (type code, clr type, whatever).

6. Array entries can be cache aligned (i.e. struct with layout padding to 64B).

Easiest to get running is single producer, multi consumer. Should get 100s of millions per sec on moderately powerfull hardware. 
1PMC can be done pretty much lock free. For multi producers, there are ways to make it lock free (i.e. allocate sections of stretches for
