The Win32-based support is still in 2.5.0 and is unchanged (it will be
dropped in 2.6.0 once we drop support for C++98/03). But by default in
2.5.0 we don't use it, instead using the C++11 threading support. This
is controlled with the ODB_THREADS_* macros, for example:

I will again suggest that you try 2.5.0 and see if that makes a
difference.
