Trying to debug a problem involving threads just now, it turned out that the version of the diagnostics going to my debug.log was getting data in a different order from the version going to the debug console. Now I open and write to debug_fp by going directly to the Win32 API instead of via a buffering userland stdio, and that seems to have solved the problem.
