erl_send

• in bif.c
• calls do_send
• otherwise handles the erlang side of things, returning the right thing, bumping reductions, etc.

send3

• in bif.c
• also calls do send and seems to have some overlap with erl_send
• can likely do this without understanding the difference fully

This file provides a simpler gen-server template for emacs' tempo mode.

To use it, drop the following:
`(load-file "/path/to/gen-server.el")`
in your .emacs or init.el or whatever somewhere after your erlang-mode initialization (so after package init if you're using packages).

It defines a function called `tempo-template-gen-server` which you can access from M-x as per usual.

This is all right as we're entering the function where the data is seen as corrupted.

this works on my machine, against a local devrel cluster backed by elevedb

check afterwards with:

curl localhost:8091/buckets/baz/keys?keys=stream

keys seem to be durable until one does a get on them, then they vanish.
