This is expected. test_tools just runs a large number of subprocesses. Some subtests proceeds a large number of Python source files as test_tokenize and test_lib2to3.

Maybe it would be better to run and report tests for different tools as separate tests (test_tools.test_pindent, test_tools.test_unparse, etc), but allowing to run a group as a whole. Does unittest or regrtest support this?
