Summary: Python 2.5+ skips while statements in debuggers

Initial Comment:
Starting with Python 2.5, debuggers pass through a "while" statement on its declaration, but never return to it during the remainder of the loop. They should be able to return to the "while" statement as it has an evaluative step in it. This has several important implications: one may not check the state of variables at prior to their evaluation in the "while" statement, and any breakpoints set on the "while" statement are ignored once within the while loop.

Python prior versions (2.4 and below) exhibit expected behavior in that the "while" statement is returned to after each successful iteration through the loop, and breakpoints on "while" statements are honored.
