sl@0: * Description: 
sl@0: * This maps Symbian OS memory management onto Icu Umemory functions
sl@0: * Memory is allocated from the shaper internal heap, which has been saved in the TLS.
sl@0: * If there is no memory available these memory functions leave, this is caught in the shaper wrapper.
sl@0: * For debugging there is an alternative set of functions which log memory allocations
