+1 There is where it belongs architecturally IMHO, thanks for pointing 
this out, I wasn't aware.

Even better: prevent flushng alltogether by making a 
CocoonIntermediateStream that extends the output stream, and that does 
nothing on flush, and instead uses an Environment-protected method for 
flushing, so we can play safe.

+1 and make it configurable.

At least we can see how it works.
Decoupling from the real stream gives us nice advantages it seems.

Running modes is a nice idea that we already had sometime back, and that 
now fortunately came back.
Basically with a single param it should be able to switch configurations.

Hence we can switch from a programmer env conf to a production one quite 
easily.
