+CPython crashers
+================
+
+This document ways to crash CPython 3.5, or get completely unexpected
+and undocumented results, or leak memory, etc.
+
+
+* _PyGen_Finalize() should not fail with an exception
+  http://bugs.python.org/issue27811
+
+* PyFrameObject.f_gen can be left pointing to a dangling generator
+  http://bugs.python.org/issue27812
+
+* os.scandir() returns an iterable object that should not be used
+  from multiple threads.  Doing so can e.g. cause one thread to
+  close the dirp while another thread is still using it.  This is
+  likely to crash.  Similarly, the test for (!iterator->dirp) at
+  the start of ScandirIterator_iternext() is only done once even
+  if the following loop runs two or three times because of "." or
+  ".." entries.
+
+* os.scandir() direntry objects should not have stat() called from two
+  threads concurrently.  It will make two stat objects and leak one of
+  them.
