- 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.
