[Python-Dev] test coverage

[Neal Norwitz]

I've been doing a bunch of testing using the regression tests
and have tried to improve the test coverage.  I've made some
progress.  Overall, the regression tests do a pretty good job.
Below are all the functions that are not currently covered by
the regression tests in Objects/ Parser/ and Python/ (Modules/
has too many at this point).  This list may not be perfect,
but should be pretty close (some tests failed:  test_new,
test_funcattrs, and test_symtable).

I don't know how many of these can be reached from within 
the python (interpreter), some may only be callable from C code 
which embeds python.

After improving test coverage, I'll go back and run purify
to see if there are any new memory leaks.

Sorry, the list is kinda long.  Let me know if there's a better way 
to distribute this info.
