    14 * Description:

    15 * This maps Symbian OS memory management onto Icu Umemory functions

    16 * Memory is allocated from the shaper internal heap, which has been saved in the TLS.

    17 * If there is no memory available these memory functions leave, this is caught in the shaper wrapper.

    18 * For debugging there is an alternative set of functions which log memory allocations
