[ACTOR] actors.lisp and actor.lisp are important examples

[adlai]

Describe the bug
If the underlying CSP library is built according to various presumptions, then the old and different actor.lisp and actors.lisp files will exhibit strikingly different behavior, that could cause hard failures of dependent code.

To Reproduce
Steps to reproduce the behavior:

1. Copy out old 'actor.lisp'
2. Copy out old 'actors.lisp'
3. git bisect --work --your --magic
4. File new issue and write test cases all teh fuckng time!!

Expected behavior
Minimal test cases resembling obscene user stories; Sophie-Germain prime-sieve orgy.

Screenshots or Error Logs
Text is preferable over screenshots, unless you edit the screenshot to highlight the failure.

System (please complete the following information):

• Hardware: [all]
• OS: [any]
• Compiler [any ... and all]
• Version [... lambda-adic suicide]

Test Suite
If you have already written tests, please include the output from running the test suite on your target system; if you can't copy output on your target terminal, please provide a verbal summary, including whether it completed and where you subjectively noted most of the resource consumption using your peripheral observations. Note that the test suite might not catch any specific unit failure, and/or might use different fixtures in the cloud than the one you imagined before writing them yourself, and will usually be invoked using (asdf:test-system "chanl").

Next, consider whether these belong in fixtures or ASDF-local quicknames

#28 adds the files

#29 should actually do something using them, rather than only publishing like "here is hairball, leach out the Melena pleasanta"

They could be compared against memento-mori.lisp, the main file from that project; however, the purposes of the two projects seem different. It appears that Kat was specifically working towards Erlang, whereas my inspiration was Ada.

Incorrectly closed by excessive GitHub automation; this Issue should remain open as a reminder that those two files are ad-hoc, undocumented, and mostly untested.
