-----------------------------------------------------------
Big thanks for taking the first crack at this. I'm going to think on this some
more, but here are some initial thoughts to improve what you put together:
- Handle exit/return codes in a configurable way
- Add details to the tuple (timestamp, path, hash of path, return code)
- Provide arguments to the script* pulled from the tuple
- Whitelist input so it can only contain something like "[0-9A-Za-z_./]+"
- We should attempt to restrict the access of the executing thread (security
manager?)
\* This needs thoroughly vet and understood.

for this and will report back when I have more details.
