To try to resolve your issue you should use TMemIniFile and invoke Rename()
before freeing the TMemIniFile (or invoking UpdateFile explicitly) to save
to the temporary file.

TMemIniFile is just TIniFile with some extra methods and with CacheUpdates
defaulting to True. They parse the whole ini file in the constructor, so
values are always read from memory.

P.S. Although these classes are meant for compatibility with
Delphi/Windows, maybe they should provide extra methods with correct
exception handling and "atomic" saving with temporary file?
Or maybe someone can recommend alternatives?
