How many hunks do we need, well, today I want 8 for 4.2 and 16 for

hunks.
Or, so that is just an off the cuff proposal to get the discussion
started.
Thoughts?
Will use C++ help or hurt compiler parallelism? Does it really
matter?
My 2c.
I don't think it can possibly hurt as long as people follow normal C++
coding rules.
Contrary to C there is no single general coding style for C++. In
fact for a project
of such a scale this may be indeed the most significant deployment
problem for C++.
Lots of threads communicating a lot would be bad.
This simply itsn't true. The compiler would be fine having many
threads handling a
lot of data between them in a pipelined way. In fact it already does
just that,
however without using the opportunity for paralell execution.
