If a warnings filter has been installed which turns warnings into

The list returned by C{flushWarnings} includes only those
warnings which refer to the source of the function passed as the value
for C{offendingFunction}, if a value is passed for that parameter.

Warnings emitted by a function defined in a file which has been renamed
since it was initially compiled can still be flushed.
This is testing the code which specifically supports working around the
unfortunate behavior of CPython to write a .py source file name into
the .pyc files it generates and then trust that it is correct in
various places. If source files are renamed, .pyc files may not be
regenerated, but they will contain incorrect filenames.

Subsequent emissions of a warning from a particular source site can be
collected by L{_collectWarnings}. In particular, the per-module
emitted-warning cache should be bypassed (I{__warningregistry__}).

L{_collectWarnings}'s behavior is not altered by the presence of an
object which cannot have attributes set on it as a value in
C{sys.modules}.

If the dictionary passed to L{_setWarningRegistryToNone} changes size
partway through the process, C{_setWarningRegistryToNone} continues to
set C{__warningregistry__} to L{None} on the rest of the values anyway.
This might be caused by C{sys.modules} containing something that's not
really a module and imports things on setattr. py.test does this, as
does L{twisted.python.deprecate.deprecatedModuleAttribute}.
