We use _beginthread. I don't remember exactely how it broke, but it did. Try
using the below instead of CreateThread.

// NOTE: if you don't need the returned handle, close it or
// leaks will occur. Closing it doesn't kill the thread.
HANDLE h = (HANDLE)_beginthreadex(NULL, 0, thread_start, arg, 0, NULL);
if(h)
CloseHandle(h);

From MSDN:
"A thread in an executable that calls the C run-time library (CRT) should use
the _beginthread and _endthread functions for thread management rather than
CreateThread and ExitThread;"
