coalesce stream output in the notebook...

coalesce stream output in the notebook This merges consecutive outputs on one stream into a single output. Essentially, it applies the same merging that we do visually to the content stored in the notebook document. This results in a massive performance improvement in load-time and storage size for notebooks that have many calls to `sys.stdout.flush()`.

      """Utilities to enable code objects to be pickled.

      Any process that import this module will be able to pickle code objects.  This

      includes the func_code attribute of any function.  Once unpickled, new

      functions can be built using new.function(code, globals()).  Eventually

      we need to automate all of this so that functions themselves can be pickled.
