unicorn 4.1.0 - small updates and fixes
* Rack::Chunked and Rack::ContentLength middlewares are loaded
by default for RACK_ENV=(development|deployment) users to match
Rack::Server behavior. As before, use RACK_ENV=none if you want
fine-grained control of your middleware. This should also
help users of Rainbows! and Zbatery.
* CTL characters are now rejected from HTTP header values
* Exception messages are now filtered for [:cntrl:] characters
since application/middleware authors may forget to do so
* Workers will now terminate properly if a SIGQUIT/SIGTERM/SIGINT
is received while during worker process initialization.
* close-on-exec is explicitly disabled to future-proof against
