+- Issue #28387: Fixed possible crash in _io.TextIOWrapper deallocator when
+  the garbage collector is invoked in other thread.  Based on patch by
+  Sebastian Cufre.

   file with compression before trying to open it without compression.  Otherwise
   it had 50% chance failed with ignore_zeros=True.
