c2cfbcc8d4
This macro is used to implement global serialisation, typically by disabling IRQs. On the unix port, if threading is enabled, use the existing thread mutex (that protects the thread list structure) for this purpose. Other places in the code (eg the scheduler) assume this macro will provide serialisation.
