[undertow-dev] Async/Rx approach in HttpHandlers

[Girish Sharma]

I read through the code and did some other reading too. But while exploring
on stackoverflow and such, I came upon this [0] question.
I am now assuming that since author here did not mention a separate
thread-pool, the worker thread pool was used up for the the sleep statement
as well and thus his concern?
More interesting however is the reply where the person who replied claims
undertow is not meant for such cases and mentions his fork undertow-async
[1].

Any thoughts around that?
