[boost] boost::mutex::scoped_lock: behaves differently under Windows and Linux

Running the following bit of code under WinXPPro prints:

Acquired first lock on mtxTest
Acquired second lock on mtxTest

and exits.

Under Linux RH9, it prints:

Acquired first lock on mtxTest

and deadlocks.

To me, the Linux behaviour makes perfect sense. Why doesn't it behave in the
same way under Windows?

#include <boost/thread/thread.hpp>
#include <iostream.h>

int main(int argc, char * argv[])
{
  boost::mutex mtxTest;

  // Initialise a scope to test scoped locking
  {
    boost::mutex::scoped_lock lock1(mtxTest);
    cout << "Acquired first lock on mtxTest" << endl;

    boost::mutex::scoped_lock lock2(mtxTest);
    cout << "Acquired second lock on mtxTest" << endl;
  }
  return 0;
}
