With old SQLite versions, _sqlite3_result_error() sets a new Python exception,
so don't restore the previous exception.

while adding the traceback, because it may call indirectly a Python function
and Python functions must not be called with an exception set.

In the case of the issue #18609, _ctypes_add_traceback() called the iso8859-1
decoder which is implemented in Python. Python has a ISO-8859-1 codec
implemented in C. It is not used because PyUnicode_Decode() only uses the C
codec for other names (aliases) of this codec ("latin-1", "latin1" and
"iso-8859-1").

when removing references to temporary build files.  This is not an elegant
solution but it does isolate changes to just build-installer.py.

We must only lower the soft limit, since lowering the hard limit makes it impossible to raise it back at the end.
(this could prevent core dumps from being generated when the test suite crashes)

Patch by Neil Schemenauer, minimally modified.

(it was wrongly classified in the pending calls test case)

It creates a refleak in subinterpreters, as atexit callbacks aren't triggered at their end.
