Does anyone have a good description of how long a given Thread lives
in the context of a request to a RoR application? Specifically:
Do I know that a given request only uses one Thread? (unless I
explicitly fork another one in my code)
Do I know that a given Thread only lasts for one request?
If I cram some data into Thread.current early-on in processing the
request, do I know that this data will be available to objects later
in the request, and the data won’t be available to (or overwritten
by) another request?
