Hi Farid,

This change appears to have cleared up the original issue. However, with =
multiple threads the test now sometimes crashes with the following error:

terminate called after throwing an instance of 'std::runtime_error'
  what():  /home/mbrown/stdcxx/src/setlocale.cpp:130: =
__rw::__rw_setlocale::__rw_setlocale(const char*, int, int): bad locale =
name: =22PY=22

The name of the locale varies and is sometimes garbage so it might be =
caused by some memory corruption.
