	Hi.  I'm trying to work out bottlenecks.  Shmalloc must lock in some
    way, in order to allocate unique blocks, even when calls to shmalloc are
    made concurrently.

	Does anyone know whether shmalloc locks *all* processes, within its
    body (ie. whatever other processes are doing), using something like
    m_lock(), or does shmalloc lock only within itself, allowing other
    processes to continue unless they call shmalloc.

	Please can anyone let me know?  Does anyone know?!

	Thanks, in advance, Simon.
