You forgot to test myHandle and make sure it points to valid data when
MemHandleNew returns. 1300 bytes is a rather big chunk of memory for such a
small device. After you begin to fragment memory, the possibility exists
that you might not be able to allocate that large of a chunk (it will also
depend on which version of the OS your app is running on).
