[issue7023] Marshal doesn't release GIL while dumping

[zengke]

New submission from zengke <superisaac.ke at gmail.com>:

If marshal.dumps() is handling a large data, It keeps acquiring the GIL
and may take several seconds, Other threads therefor are blocked.
marshal.loads should also be friendly to other threads.
