  Make the memory-window conrol structures global
  
  Up to now, the idea was that the user would do all the operations for
  one repository in the same thread. Thus we could have the
  memory-mapped window information thread-local and avoid any locking.
  
  This is not practical in a few environments, such as Apple's GCD which
  allocates threads arbitrarily or the .NET CLR, where the OS-level
  thread can change at any moment.
  
  Make the control structure global and protect it with a mutex so we
  don't depend on the thread currently executing the code.
