[issue7615] unicode_escape codec does not escape quotes

New submission from Richard Hansen : The description of the unicode_escape codec says that it produces "a string that is suitable as Unicode literal in Python source code." [1] Unfortunately, this is not true as it does not escape quotes. For example: print u'a\'b"c\'\'\'d"""e'.encode('unico

New submission from ttsiod : I found a nice yield-based implementation of the sieve of Eratosthenes. I tried to find the last prime number less than 1.000.000 (1M) - so I had to increase the recursion limit (via sys.setrecursionlimit). It seemed to work - but after running for about 3 minutes,
