79d37ae979 Clear potential ref cycle between Process and Process target (#2470)

Besides Process.join() not being called, this was an indirect cause of bpo-30775.
The threading module already does this.

buildbots.

bc50f03db4 bpo-30414: multiprocessing.Queue._feed do not break from main loop on exc (#1683) 
* bpo-30414: multiprocesing.Queue._feed do not break from main loop on exc

Queue background running thread was not handling exceptions correctly.
Any exception occurred inside thread (putting unpickable object) cause
feeder to finish running. After that every message put into queue is
silently ignored.

source files of modules which don't provide command line interface.  Fixed
shebang lines in the unittestgui and checkpip scripts.
